[Kano]

Why do you need a random generated compressfile? If you want random data you can pipe it directly too...

[Michael]

Because this test is ran multiple times, randomly generating it each time may be a waste.

[apaige]

More importantly, simply reading from /dev/urandom already takes a lot of CPU time. It would completely skew results.

[Kano]

Also it is not fully known if the input data has to be different to /dev/zero. Try zero and compare the values, input from that is very fast.

[Michael]

I had tried that before and it had impacted some tests.
