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 ?
For what I have been experimenting, and with the default configuration, yes.
I mean, if you go to the website, download both VMs, and run, I think that yes. Maybe compiling Linux vms with particular flags in the configure, you may have better results.
I said this in another thread I people said I was talking bullship, so, I won't talk any more.
I let you two links in case you are interested to read:

��Shouldn't a Linux server box be faster at networking/IO/CPU than a MacBook Pro running the full Mac OS X GUI ?
not necessary. Because you depends on the VM I think.
��
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 ?
yes.�� First the flags when compiling the VM. Check the version of GCC.
Then you can check all the parameters of the GC and etc...but I have no idea how to tune this.
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
