(PECL pthreads >= 0.0.33)
Thread::getPeak — Return the peak number of Threads.
Return the peak number of Threads executing concurrently in the current instance of PHP. Some system administrators choose to limit the amount of Threads an instance of PHP can create. If enabled the maximum number of Threads the current instance can create is returned by a call to Thread::getMax().
What counts as "an instance of PHP" depends on the current environment PHP and pthreads are executing in.
