Yes, this is true. There are some computers that I've run OpenSolaris on where it totally blew Ubuntu away in terms of speed (multi-core computers with 4 gigs of RAM anyone?). The OpenSolaris Live CD definitely boots up faster than KDE Kubuntu Live CD on most dual core machines, I'll say that. However, on one of my home computers that is a Pentium 4 with 500 megs of RAM and Solaris doesn't run fast on it at all. And trying to run it on my AMD Turion ML-34 based laptop with 500 megs of RAM, it just runs so unbelievably slow that it takes almost 10 minutes to move the mouse from one side of the screen to the other when it's in "Live CD" mode (probably because the CD drive read speed is slow and there's not enough RAM to load the entire CD into memory).
One of the biggest things that slows OpenSolaris down IMO is when it runs in 32-bit mode instead of 64 bit mode IMO. ZFS really kicks the butt of every other file system (except maybe Reiser FS?) in terms of speed when it has 64-bits and a little bit of RAM to play wityh. Solaris also likes multi-threading. I've noticed it seems to deal with massive multi-threaded jobs on multiple cores / CPUs better than most other operating systems do. Anybody else have any experiences that make them agree / disagree with this? -- This message posted from opensolaris.org
