Zope under vmware is too slow
Dear all, I must install zope under vmware, but there are big speed degradation over plain machine. Does somebody have some tip&tricks to run Zope under VMware faster? Many thanks, J. Lukesh

Many thanks, J. Lukesh It's probably not zope that is slow but disk access. Does it have enough RAM memory, is it swapping to disk often, etc?

Very much of RAM is free at host and guest, both physical and virtual disks does not swap. Speed degradation is to 15% of speed at original server, but vmware have 4x more CPU power. New Zope 251 server is starting about 5 minutes, whole system performance (from ssh console) is very poor, like IBM XT. It is very gratifying that somewhere is running zope under vmware fast, so I need to find where is the bottleneck. Do you have some tips to run Linux under vmware faster? How about acpi/apic?

What means "too slow"...please come up with some numbers...If you give your virtual machine very little memory then it will of course be slow...although other configurations can also influence the performance. Of course virtual machine are a bit slower than real hardware (usually <5-10%) but I have never experienced any major performance issues with Zope under Vmware. -aj
