Hi, I am very happy that I managed to create a very small deploy image based on Pharo-1.1-11400-rc2. This image contains all of Seaside and Glorp/PostgreSQL and is still only about 12Mb. All this thanks to ScriptLoader's #cleanUpForProduction. Thanks a lot to all who made this possible. I noticed however that this image is handling my HTTP/Seaside benchmark consistenly faster on my Mac, about 80 to 85 req/s (Mac OS X 10.6.4, 2.4 Ghz Intel Core 2 Duo with 4GB RAM) than on my server (RHEL 4 (update 7), 2 Ghz AMD Opteron 175 Dual Core with 4GB RAM), about 55 to 65 req/s. On my Mac I use the Squeak 4.2.4beta1U VM, on my server the Squeak-4.0.3.2202 Unix VM. Next I tried the Squeak-4.0.3.2202 VM on my Mac. This resulted in about 60 to 70 req/s. Is it normal that the Unix VM is slower than the Mac VM ? Shouldn't a Linux server box be faster at networking/IO/CPU than a MacBook Pro running the full Mac OS X GUI ? Is there anything simple (low hanging fruit kind of stuff) that I can do to improve performance, either using command line options to the VM or using settings at the image level ? I currently run the VM with: Squeak-4.0.3.2202-linux_i386/bin/squeak -vm-display-null -vm-sound-null deploy.image What are others using in the Seaside deploy area ? Thanks, Sven
