Hi. We have SSRS 2012 installed in a new VM on new hardware backed by a new SAN. Reports run much slower than on the very old hardware with SSRS 2008. I'm pretty sure something is wrong with configuration or setup someplace. I looked at the many counters in the VM, but can't find anything obvious.
Anyway, I wanted to compare the VM SSRS 2012 to physical SSRS 2012, so I used my desktop. My desktop is much faster with the same reports and external sources. My desktop has more cores then the VM. I want to limit SSRS on my desktop to use the same number of cores as the VM. I set the affinity in SQL. I also tried to set the affinity in task manager on the reportingservicesservice. As soon as I run a report, the affinity of the process goes back to all cores. So it appears the service sets the affinity. I also notice that the affinity of the SQL service shows all cores in use.
Is it possible to limit the cores used by SSRS? If the SQL affinity setting limiting the cores used even if the affinity on the service is showing all cores?
Thanks.
