Could just as easily launch N sub-processes from run-tests.php as well.
I compile php in a VM with -j 40 on a dual core VM powered by quad core chip...
The number of simultaneous tests doesn't need to line up with CPU counts...

Nuno - just a PS to the last note. It is (mainly) the task allocation
across processors which means that running tests in parallel on a 4-way
machine is not 4 times as fast as running them in sequence.
Here are some results from a run on my 2-way Mac -

Hi Nuno
Hi,
Here you have a dump of a run of PHP_HEAD in the gcov machine (almost
13k tests) without valgrind:
http://gcov.php.net/~nlopess/dump_PHP_HEAD_z4.txt
It was run with -z 4. However, the reported CPU usage is only 213%
(instead of ~400%).
I spent a lot of time this weekend trying

Hi Nuno - did you ever get a chance to look at the parallel version of
run-tests? I had some free time to work on it last week so REDIRECT is
now implemented, I have tested it using ext/pdo_mysql and ext/pdo_sqlite.
I'm testing using about 8000 phpt tests and getting the same results as
run-te
Alright, thanks for the reply!
I'll try to have a look at the code and give it a try next weekend.

Hi,
nice work, out of curiosity I tried on a VM with 24 virtual cores:

I just have a few concerns about this:

HI Felipe - a couple of updates.
1) Is your ~/dev/php5_4/sapi/cli/php built --with-zlib?
2) This test uses the php-cgi, are you setting it with an env
variable? Or relying on run-tests.php to find it (it should do that)
Even if it is missing zlib function that is causing the initial error,
