Subject: strange stats
From: Giacomo Tesio <giacomo@tesio.it>

Hi, I've noted a strange behaviour in stats during the system compilation.

When I run `mk install` at the rio terminal, stats shows that load,
context and syscalls grow to 100% untill the window buffer is full and
then go down to the previous values. If I scroll down the window, the
stats grow up again until the the window is full, than drop again.

Instead if I send stdout to a file, that stats remain 100% till the
compilation completes.

Such behaviour makes me wonder if writing logs to the console is
blocking the compiler.
Is this the expected behaviour?


Moreover, does the compiler benefit from multiple cores?
`xl top` at xen dom0 shows the cpu usage of the 9front vm at 112% but
I did expect it around 400%, since I assigned 4 cores to the system.
