Ever wondered what it takes to debug performance issues on a VMware stack? How do you figure out if the performance issue is in your virtual machine, or the network layer, or the storage layer, or the hypervisor layer?
Here’s a handy tutorial that showcases a systematic approach for troubleshooting performance using tools like Esxtop, vSCSI stats and Net stats on a VMware stack. The tutorial also talks about some very useful optimizations and performance best practices.
