Subject Re:HW requirements for a large-scale test performance
Date Thu, 07 Nov 2013 01:38:37 GMT
It's difficult to estimate for Jmeter.
for CPU, it depends on the sampler's deal. complex or simple, correspond to diffirent cpu
for RAM, it's not easy to estimate for it's java implementation. the jmeter just use memory,
when the memory available is not enough, JVM just do GC.
so u can't caculate one thread use how much memory.
As opposiste, in Loadrunner, you can examine a mmdrv.exe process use how much memory, to caculate
the memory usage per user.
