Re: Comparing Java Web Server performance
I would ignore the hyperthreading and go with the Opterons. Depending on
the process's thread patterns the HT can make a difference or be totally
useless. I like to use this analogy. Threads execute by putting their
"people" in a train of cars and sending it for a loop through the roller
coaster. Hyperthreading lets u put somebody else's people in any unused
cars. It's too much of a crap shoot for me and who knows what other kind of
overhead it's producing. Not to mention how it complicates figuring cpu
usage. The only way I can think to compare them is to do benchmarking with
and without the HT turned on. It's really application specific.
