What are some steps/tips/tools I can test performance with? Of the 4 esxi servers only one of them will run our terminal servers where users dont complain about it being slow. Two of the servers are fairly close in hardware specs, R620 and a R630. The other two are R610s. One would think our TS should run fine on the 620 since it is close in hardware specification to the 630 but they run about the same as if they were on the 610s, If I migrate the TS's to the 630 it runs just fine.
