Re: [xep-support] images performance issue

During this test we also perform monitoring of system params.
With graphic
CPU load 1%-10%
Free memory about 200mb

Without graphic
CPU load 50%-100%
Lot of free memory.

I am not sure this because of memory, we also run this build on Laptop,
with 512Mb and slower processor. It takes about 2min to generate the
same PDF.

Probably the memory on this machine can be slower, but I can't imagine
what speed it should have to increase build time from 30 seconds to
30minutes.
Thats why I am asking what can cause such slowdown.
