This is probably obvious but I decided to try this myself: Should one run web2py with Pound on multi-core server?
probably yes if you deal with concurrent connections.. This is my config: 2.6.31-19-generic-pae Intel(R) Xeon(R) CPU E5410 @ 2.33GHz Ubuntu 64bit one processor with 4 cores disk is serial ata, with performance around this: #/sbin/hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 268 MB in 3.01 seconds = 88.96 MB/sec This is slow. This is one SATA disk. I used mysql-5.1 for "writing" tests. I run it on the same machine. Also POUND. "ab" command runs on my 32bit ubuntu laptop with 2.5 Ghz Core2Duo. Server and laptop are connected via Gigabit ethernet directly. I did 12 concurrent connections with 2000 calls, and then 1 connection with 2000 calls test for every case. Application was compiled. I set migrate=False.
