I migrated a number of servers to 64bit about 12 months ago, and then migrated them back to 32bit some 9-10 months later. These servers were all the same - AMD 64bit, 2Gb RAM. My thinking was "64 has to be better than 32", if nothing else then because it's 64-bit OS/software on a 64-bit CPU. Well, I was wrong. Because of the increase in memory-usage with 64-bit openSUSE, each server ended upn being able to handle less load running 64bit than 32bit.
Are you saying I should now downgrade my 11.1 installation to the 32-bit version? I waited *forever* to upgrade my increasingly cranky previous system and when I took the plunge, I installed the 'native' 64-bit flavor!
No, whether you're better off with 32bit or 64bit depends entirely on your system and your software. A heavily loaded database server with 32Gb of memory will no doubt be better off with a 64bit OS and apps. My servers only have 2Gb memory each, and because I'm running several hundred processes on each server, I ended up having room for less when everything was 64bit. -- /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
