I created a small utility for Windows, which will give a lot information about some started process. In the past I used ptime ... but this tool only measures the time and nothing more.
If you want some more advanced statistics about some codec, it will not help you 
I have read some windows documentation and created an own small open source tool for it.
The output looks like this:
Code:
Command: 7z a silesia.7z -mmt=off -mx15 silesia
TIMES in milliseconds
RunningTime................. 32104
UserTime.................... 31793

WriteOperationCount......... 34
OtherOperationCount......... 115
ReadTransferCount........... 211939037
WriteTransferCount.......... 58043652

I just named it wtime and released version 1.0. It may help also others with doing some testing of compression/decompression or other tasks .... I am using it for creating csv files, which then are used for creating diagrams.
