Free (Libre/Open-Source) Software that lets you control per-process CPU usage, released under the GNU General Public License v2 (not v3). Portable; installation not needed. [français, 日本語]
BES is a small tool that throttles the CPU usage of the process you “target”: for instance, you can limit the CPU usage of a process which would use CPU 100%, down to 50% (or any percentage you’d like). With this, you can use other programs comfortably while doing something CPU-intensive in the background. BES has also helped various gamers as a handy “anti-freeze” agent, though that is not the original purpose of BES. Well-known examples quick-fixed by BES include The Witcher 3 + BES, dual-core (2015); Kingdom Come: Deliverance + BES; and Red Dead Redemption 2 + BES, 4-core (2019). While BES might just happen to help you more or less, some users say it doesn’t work for them at all.

This chapter isn’t an apologia; it’s an anatomy. Piracy meets needs—access, cost, immediacy—but it also erodes revenue for creators and complicates legitimate distributors. The Martian’s migration to Filmyzilla reflects structural gaps: limited regional dubbing rights, late or expensive streaming releases in South Asia, and a hunger for content that official channels weren’t always satisfying quickly enough. A film shifts when its language changes. Dubbing is not neutral: it reframes jokes, alters cadence, and can repurpose characters for different cultural sensibilities. Mark Watney’s wry, understated humor becomes something else when rephrased into Hindi: idioms swap, expletives soften or intensify, and comic timing pivots on the voice actor’s choices. Supporting characters—NASA engineers, astronauts—acquire a different communal rhythm when their spoken language is localized.
Prologue: How a Red Planet Became Everyone’s Backyard When Ridley Scott’s The Martian landed in 2015 it arrived as a clean piece of cinema engineering: a survival story welded to science, threaded with humor, and fuelled by Matt Damon’s stubborn likability. For many viewers it was a classical Hollywood export — high production values, a triumphant score, and a tidy emotional arc. But films have long lives beyond their first theatrical run. They migrate through streaming catalogs, cable repeats, second-run theaters, and then a wilder, internet-born afterlife: the world of pirated downloads, torrent hubs, and sites promising instant access in local tongues. Enter the Hindi “Filmyzilla link” — an ugly phrase that belies an intriguing cultural trajectory. This is the story of how a mainstream sci‑fi drama traveled from multiplex screens into the hands of a billion‑plus language speakers, remixed by translation, appetite, and illicit circulation. Chapter 1: The Translation of Taste — Why Hindi Viewers Hungered for The Martian Hollywood sci‑fi is no stranger to Indian audiences. Blockbusters with spectacle sell well; but The Martian succeeded differently. It offered accessible science, a focused central character, and above all, an emotional center anchored in resilience rather than just spectacle. Hindi viewers — urban and aspirational, rural and curious — found in Mark Watney’s ordeal a universally intelligible human struggle: loneliness, ingenuity, hope. The film’s modest scale (relative to globe‑shaking alien invasions) made it easier to translate—literally and culturally—into Hindi. Dubbed versions and subtitled files filled demand: people wanted it with familiar cadences, jokes rephrased, and emotional beats rendered in a tongue that softened the film’s clinical edges. Chapter 2: The Piracy Pipeline — From Box Office to Filmyzilla Link The pipeline is mechanical and fast. Films leave theaters, distributors license territories, and then digital copies circulate. Where legal distribution lags — due to rights, delayed dubbing, or lack of affordable access — piracy steps in. Filmyzilla and similar platforms are part of that shadow ecosystem: websites and trackers that aggregate downloads, labeled with enticing tags: “Hindi Dubbed,” “HQ,” “720p,” “Filmyzilla link.” The Martian’s presence on such sites is predictable: a high‑quality Hollywood title, demand from Hindi speakers, and the perennial incentive for free, immediate access. the martian hollywood movie in hindi filmyzilla link

Reported by Zijian.DebugActiveProcess, as opposed to limiting it “thread by thread” (Mode 0) using SuspendThread. The new option is available on the Confirmation dialog box in GUI, or in command line like this:bes -J "C:\your\target.exe" 10;100;0;1Basically, just unzip the zip wherever you like and run bes.exe. You don’t need to install it.
Note: If you just run BES and it works for you, that’s fine. But you may have to run bes.exe as admin (right click > “Run as Administrator”), especially when you need to limit a process running as admin (otherwise, such a process won’t show up in the “Target” list). I know this may sound scary — it’s not a good idea to run a random exe as admin. The thing is, BES needs some privileges to do its job, i.e. suspending and resuming threads that don’t belong to its own process. If its right is too limited, it can’t even see exactly what other processes are running on your computer.
When you don’t need it anymore, just delete the whole folder that you unzipped, and everything will be okay.
For more info: do some web search to see what others are saying about BES. There are (unofficial) guides on the Internet, written in various languages by users. BES itself supports a few languages, e.g. French, Japanese, Finnish, Chinese.
NOTE: This page (the official site of BES) has existed for about 15 years, originally having a tutorial with a lot of images. However, due to the RDR2 mess in Novermber 2019, too many RDR2 players are coming here now, trying to get BES, which could cause a server down and/or too much transfer. Because of this, I have made this page plain and text-only (for the time being) to save server load and bandwidth. Previous versions of this page are on web.archive.org.
As of July 12, 2023, https://mion.yosei.fi/BES/ (Finland) and http://mion.faireal.net/Bes/ (US) are (almost, if not completely) identical, mirror sites on different servers. Use whichever you like.

BES is free (as in freedom) software, and it happens to be free-as-in-gratis too. It’s just one of my hobby projects, recreational and not-for-profit; as such, you do NOT need to pay for it at all. Many web pages force you to pay indirectly via ad companies, monetizing your privacy; which doesn’t happen here either. Not on my watch. If you know how to get Monero without KYC, you’re free to send me some.

If you’d like to use Paypal: you can visit https://cal.huc.edu/ and support the CAL project via Paypal. CAL is a project to make a huge online dictionary of the Aramaic language. Although hosted by Hebrew Union College, the project is not necessarily Jewish (one of the main dialects of Aramaic is mostly Christian). It’s not my project, and has nothing to do with BES, but it’s a great project any language lover may want to support.
Alternatively, instead of sending a donation to me or someone else, you can simply be a bit nicer to your friends/family members/etc. This may sound strange and/or corny, but I think basically it’s the same thing, because that way, in the big picture, you’re making the world where I live, a slightly better place. Equivalently, you could also try to be slightly more tolerant to your “enemies,” refraining from using a religion or non-religion as a weapon.
It is now confirmed that the recent Tor-blocking was caused by Imunify360. Fortunately the hosting company is a privacy-focused and Tor-friendly one, and has solved the said issue permanently by tuning this WAF (web application firewall), disabling its overzealous access blocking.
If you’re interested in online freedom and anonymity, you may want to visit e.g. the website of the Free Software Foundation (FSF) and check their articles like “We have nothing to hide, only everything to protect”. Or visit the website of the Electronic Frontier Foundation (EFF) and read “How to: Use Tor | Surveillance Self-Defense”.
Tor is not perfect, but it’s a great tool if used properly. Tor network (nodes) is run by many universities and privacy advocates in various countries. If you’re privacy-aware, not happy with the current online situations, or if you’re a vulnerable user (as in minority groups, people in oppressive countries, etc.), you should definitely give it a try. You can easily use Tor Browser side-by-side, while keeping whatever browser you’re using now.
If you’re a geek, consider Tails OS, even. It’s a Linux (Debian-based) but it’s a live OS booting from a USB stick, meaning you can use it while completely keeping your Windows OS, and its GUI is very intuitive. On Tails, every Internet connection from or to it is over Tor, so basically, no one can see you. Moreover, even if your Windows machine is infected with viruses or malware, you can safely start Tails OS (using the same machine) in a clean, virus-free state. Thus it may be extremely handy in some situations, like when you’re not sure if your box is secure or compromised. (January 29, 2025)
It was unintentional but very embarrassing that our website had been blocking Tor Browser for about 2 weeks since around Jan. 9, 2025. Fortunately the problem was fixed on Jan. 23, 2025, thanks to the support team of the hosting company (FlokiNET). Now it is again possible for anyone including Tor users to freely and anonymously visit our web pages, as it should be. Of course JavaScript is not necessary to use this website. Any cookies, for tracking or whatever, are not used here. Moreover, our pages do not have any third-party contents (e.g. ads, Google analystics, Google fonts), plus always setting the no-referrer header. (January 26, 2025)
[Why people use Tor and encrypted chats]
This problem has been fixed already. See above.
Since around January 10, 2025, the company hosting this website (mion.yosei.fi) has introduced Imunify360 and Spam Filter. These components are supposed to make the server safer by blocking malicious traffic, but apparently, they are not fine-tuned properly.
Although not yet fully confirmed, it appears that, as a result, now you can not open any page of this website if you are on Tor Browser (TB).
What may happen is, when you try to visit this website using Tor Browser (TB), you’ll be shown a page that says: “One moment, please...”
Something like this is very familiar to most TB users. Rather annoying, but usually, the page you’re trying to open will be loaded normally after this, if you just wait for a few seconds. However, in this specific case, something is wrong and the “One moment, please...” page keeps reloading itself endlessly and prevents the actual page you’re trying to open from being loaded.
In short, your HTTP requests are censored, interrupted, and blocked.
Obviously, I’m not happy with this blockage, and would like to unblock TB in one way or another, keeping the pages Tor-friendly i.e. privacy-respecting. It will be best if the hosting company (FlokiNET) can figure out what has gone wrong here and solve the issue. Their support is, at least, not totally ignoring the ticket I have opened about this. Although I’m not yet sure how I may handle this in the end, I’d like you to know that the blocking is not intentional, and that I’d really like to solve this issue. As a TB user myself, I find it disturbing that more and more servers start marginalizing TB users. Of course I can see many valid reasons why Tor might be blocked in some situations, but indiscriminate Tor blocking based on no reason (or vague reasons) is, in my opinion, nothing but oppressive censorship, directly attacking our basic human rights, privacy and personal dignity, and online freedom; indirectly supporting terrible totalitarianism.
