Stress Test New VMware Infrastructure
I was performing some stress tests on Linux VMware machines for a new environment to evaluate and find the resource bottlenecks and how SAN storage reacts in terms of CPU I/O waiting before using this environment for production purpose. I got the interesting results and would like to share with you guys. The "stress" tool has been used with options shown below: # stress -c 65 -i 60 -m 25 --vm-bytes 256M -t 120m -v -c: number of CPU workers -i: number of IO workers -m: number of Memory workers --vm-bytes: allocate memory size for each memory worker(default 256MB) -t: the duration of running the test -v: make the test in verbose mode With this options, I went through 150 for 5min CPU load and almost 100 for 15min load which is pretty amazing. It has carried out in a test VM with 2 vCPU and 4GB memory. # stress -c 65 -i 60 -m 25 --vm-bytes 256M -t 120m -v top - 17:44:56 up 55 min, 3 users, load average: 151.21, 124.73, 99.78 Tasks: 254 total, 67 run
