Hi Toke,
I don't get SSDs, only spinning drives.
And as you mentioned, the impact of VMs is not that much if you use spinning
drives.
It is more the VM software that matters and thats why we use XEN and not KVM.
With some tuning of sysctrl for the VMs it performs good, but bare-metal is

Hi Upayavira,
best would be to have 4 dedicated servers, 2 for indexing (masters) and
2 for searching (slaves). Always one is online and one is standby in
case of hardware failure or update of OS, JAVA or even SOLR.
But I only get 256GB RAM machines with many CPUs which I have to share
with other

We have ~5 smaller (< 1M documents) solr set
What are you trying to achieve by using virtualisation?
If it is just code separation, consider using containers and Docker
rather than fully fledged VMs.
CPU is shared, but each container sees its own view of its file system.

Hi Shawn,

I thought other solr users are in the same situation but seams that
other users have tons of hardware available and we are the only one
having to use VMs.
Right, bare metal is always better than any VM.
As you mentioned

Dear solr users,
while setting up some new servers (virtual machines) using XEN I was
thinking about an alternative like KVM. My last tests with KVM is
a while ago and XEN performed much better in the area of I/O and
CPU usage.
This lead me to the idea to start a poll about virtualization platform
