Gents, am I reading this information incorrectly, or is this box also swapping about 128M? Swapping will quickly grind your system to a halt. I guess this all depends on how many people are connecting to your apache servers... Turn on your server-info and see :) Vasiliy Boulytchev vasiliy@xxxxxxxxxxxxxxxx
Hmmm, now that you mention it, that's a very good point. Does anyone out there know why CentOS 3 would swap out so much vs. "giving back real RAM" from buffers and/or cache? I agree with Vasiliy that it looks like the performance on this box could be pretty lame if anything important is in that swap (I would assume the OS is putting the "oldest" stuff in swap, but what if an app didn't need to get used very often and it suddenly received a request... that request could easily time out while stuff is swapping back in from disk, right?). Does anyone know a good way to see which app(s) and/or parts of the OS/libs are being put into swap vs. kept in "real RAM"?
