Hi Kl522,
I do run my test both with and without ccache. As expected, running twice or more with ccache provides some speed improvement.
But at this point I do not care much about ccache. The problem that I try to understand is the time difference when compiling as root
or as the knoppix user. Or in other words, in both cases (with or without ccache) running as root is much slower than with the user Knoppix.
Thanks for your help. Best Regards,
Gilles
