Not so. Here is a quote directly from the "Swap-Mini-Howto": "It is now feasible (in the Linux 2.5.40 timeframe) to eliminate swap devices (partitions) completely and not be penalized in performance." Performance gain proof in networking swap vs no swap: Results of netperf TCP/IP Stream performance tests on Linux/MVME-162 and Linux/MVME-167 are found here: http://www.esrf.fr/computing/cs/sysadmin/rtk/emlinux/doc/netperf/vmetcpstream.htm Performance gain proof as related to I/O. Go to the linux-audio-dev mailing list and query for "swap" and you'll get tons of info supporting my position. Go to the kernal (Developer list) mailing list and you'll find tons of info supporting my position. Lonnie, This fact is nothing new... It's been a fact since the invention of the hard drive. How can you make the claim that a swap partition on a hard drive is faster than 10ns RAM? Swap pages vs RAM is Snail vs Jackrabbit. For the record, I'll say it one more time: " I know alot of people do not want to run a system without a swap space." Lonnie, you are one of them which is fine with me. But, don't mix fact with fiction by claiming that using a swap space is a performance enhancement. It' an insurance policy for underprovisioned machines.
