In our project we were lucky enough to reach the point for performance profiling and optimization.
My colleagues were constantly fighting with time: the profiled instance being requested from the cloud and they were monitoring and then saving the screenshot and the data from performance monitor. They were not able to leave the office until the measurement typically taking 1 hour were done. We needed data from the perfmon.
I just happened to meet the adequate solution on windows.
One can define Data Collection Sets and afterwards getting data out via reports with the perfmon tool.
A sample for ReadyBoost technology profiling can be found here.
Do you happen to know the demotivational poster about premature optimization & the devil? And Mr Knuth of course.)
