The late Marshall Booth used to say the best compression test was cold start during winter. If the engine starts immediately and fires evenly on all cylinders, your compression is good. No need to spend time or money on a compression test which will only confirm that your engine is healthy.
I guess considering glow plugs when having cold starting issues would be no brainer, but this car starts on the first bump at 50 and 60° so it didn't occur to me.

My mechanic buddy thought that was good enough proof of good compression. He didn't have a suggeston about getting more power.
