* pthreadpool: Allow multiple jobs to be receivedVolker Lendecke2014-03-271-9/+10
| | | | | | | This can avoid syscalls when multiple jobs are finished simultaneously Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
* pthreadpool: Avoid a malloc/free per jobVolker Lendecke2014-03-271-54/+91
| | | | | | | | | | | pthreadpool_add_job is in our hottest code path for r/w intensive workloads, so we should avoid anything CPU-intensive. pthreadpool used to malloc each job and free it in the worker thread. This patch adds a FIFO queue for jobs that helper threads copy from, avoiding constant malloc/free. This cuts user space CPU in the local-bench-pthreadpool benchmark by roughly 10% on my system.

* pthreadpool: Fix pthreadpools with forkVolker Lendecke2014-03-031-15/+6
| | | | | | | | | | | | The current could would crash if a pthreadpool was created, deleted and the process then fork()s. "pthreadpools" is NULL in this case, but the pthread_atfork handlers are in place. This fixes walking the pthreadpools list in reverse.
