The first thing to note is the garbage collection, there are like 8 changes to the line so 8 sets of garbage collection that happen which is expensive for a .net app. We get much more processor usage for a more prolonged time and we really start to see some disk activity, write activity just has one peak while the files are written but reading stays quite high throughout the whole process. It could be that it is sql reading from disk (my demo was from a single ssd with a local sql instance) but we can see after the sql cpu settles down the green disk read line stays high so it is unlikely to be pure sqlserver.exe.
What does this tell us?
Well if you have large objects, multi-thousand line stored procs then you better get yourself some serious ssd’s to deploy from. If you have smaller objects then you’ll need CPU and memory – don’t scrimp here!
