I recently read that several NX solution vendors are now using libjpeg-turbo instead of the older libjpeg.
http://libjpeg-turbo.virtualgl.org/It's a high-speed version of libjpeg based on libjpeg/SIMD but with additional optimizations and support for 64-bit platforms (and neatly packaged into an SDK that can install on most types of x86/x86-64 systems.) It's 2-4x faster than libjpeg and GPL-compatible, so I would imagine that NX related remote desktop solutions like x2go, FreeNX and NX from NoMachine itself woul all benefit from it performance-wise.
NOTE: when I first tried libjpeg-turbo I installed it only on the client and I didn't seem much if any change. However I recently learned that actually has to be innstalled on BOTH server and client to see the performance benefit but in a recent test I saw the results of increased performance 180%. BUT - I'd still recommend running Browser based video like YouTube off of the local Client machine instead of over the Internet from a remote desktop.
<snip> That's really interesting. However, most of our installations are Debian X2GoServer but Windows X2GoClient. Is that a non-starter for libjpeg-turbo? Thanks - John
PS - Brian, may we trouble you to replace the subject (X2go-dev Digest) with the actual thread subject when you reply? That would make it much easier to sort through the piles of mailing list emails. In my for example, when busy, I only take the time to open emails with subjects where I think I can help or learn something important. Thanks - John
