Subject RE: ActiveMQ on Physical Server vs. VM
Date Tue, 28 Jan 2014 13:07:54 GMT
If you are using ZooKeeper to handle the new features of levelDB on v5.9, I would think a dedicated
NIC would increase performance if this is not shared on the physical server.  I wasn't aware
that a dedicated NIC could be utilized on a VM.  I thought this was shared with all resources
on the VM space, no?

Like with pretty much any Java app, you end up running a VM in a VM.....
Performance on IO, CPU sharing and so on will be impacted.
That doesn't mean that you couldn't scale in different ways with more VM instances instead.
