The VPS upgrade is complete. Now we have:
CPU 1.98GHZ / RAM: 1344MB
as opposed to
CPU 1.13GHZ / RAM: 768MB.
However the performance is still awful.
I just ran some command-line ImageMagick tests after the upgrade on 2
different servers and my Linux desktop using this command:
% convert cat1500.jpg -thumbnail '100x100>' -background white -gravity
center -extent 100x100 cat_thumb.jpg
On the VPS server, the command takes about 18 seconds.
On the ordinary shared hosting server it runs easily in about 1/2 second.
Then on my local Linux pc, it also completes in under one second,
perhaps 1/4 to 1/2 second.
I can appreciate that it might slower slower on the VPS server because
of how the server shares resource, but the difference I am seeing is
minimally a factor of 18, probably 36+.
Can this be? What else is in the mix that can be checked? The version
of imagemagick is even newer on the VPS account:
/home/horses/TEST% convert -version

Can anyone on the list do a similar test on a VPS server they run. The
input image is a standard 1500KB jpg.
