Slimjet 64-bit Experimental Build

Slimjet 64-bit experimental build is now available for download.

Regular installer: http://www.slimjet.com/release/sjtsetup_x64.exe
Portable version: http://www.slimjet.com/release/sjt7z_x64.exe

Chrome also introduced both 32-bit and 64-bit since V37. However, if you install the 64-bit version, it will directly overwrite the 32-bit version. You can’t have both version installed. For people who want to keep 32-bit and 64-bit version side by side, that’s inconvenient and awkward.

We have made tweaks in the Slimjet project so that the 32-bit and 64-bit version can sit side by side on the same system. They share the same profile folder unless you are using the portable version.

According to the Chromium blog, the 64-bit version of the Chromium has the following three major advantages:

  • Speed: 64-bit allows us to take advantage of the latest processor and compiler optimizations, a more modern instruction set, and a calling convention that allows more function parameters to be passed quickly by registers. As a result, speed is improved, especially in graphics and multimedia content, where we see an average 25% improvement in performance.
  • Security: With Chrome able to take advantage of the latest OS features such as High Entropy ASLR on Windows 8, security is improved on 64-bit platforms as well. Those extra bits also help us better defend against exploitation techniques such as JIT spraying, and improve the effectiveness of our existing security defense features like heap partitioning.
  • Stability: Finally, we’ve observed a marked increase in stability for 64-bit Chrome over 32-bit Chrome. In particular, crash rates for the the renderer process (i.e. web content process) are almost half that of 32-bit Chrome.

However, we doubt any average user is able to feel significant performance improvement during daily browsing activities. And it’s also worthwhile to mention the catches with 64-bit version

  • It won’t be compatible with 32-bit plugins. If you often visit sites with 32-bit NPAPI plugins, we’d advise you to stay with the 32-bit version for now.
  • 64-bit version uses more memory due to its wide word width.

The 64-bit version hasn’t gone through extensive testing yet. Be prepared for bugs and issues. If you find any problems, please report to us via the online feedback menu under Help center.

  1. Thank you very much for the 64-bit version of the browser. I find the current 64-bit version much better that v.1.2.2.0. Namely, it identifies correctly as based on Chromium 37 (not 36 as the 32-but version) and it does not crash on some HD YT movies (contrary to the 32-bit vesion). In fact, no issues has been noticed by me. Thanks!

  2. У меня 64-ка отлично работает.
    Очень шустрый браузер, большое спасибо программерам))

  3. Where the new version Slimjet 1.2.4 64-bit ??? 🙁
    I ask for the new version 1.2.4 64 bit
    Slimjet 64 bit is great browser !

  4. Slimjet 1.2.3 64-bit is way more stable on Windows 8 64-bit than previous Slimjet versions. I also notice its resource footprint is way lower than with the 32-bit edition. The browser is amazing update on the base Google Chrome build. Although as a tech head I’d love more internal option control via flags but I know I can have everything 🙂 Keep up the good work.

    1. I don’t know why you noticed smaller memory usage for 64-bit. I did a simple test here. Open http://finance.yahoo.com in both 32-bit and 64-bit. The rendering process takes 83MB in 32bit while takes 120MB in 64bit. Memory optimization and ad-blocking are both turned off to rule out irrelevant factors. You can view memory usage via the menu Tools->Task Manager.
