I encountered rrd file writing timeout(12 seconds) as the number of

So I started investigating where the performance bottleneck could be
occurring ( We have multi-core CPU and there are no cpu or I/O
bottlenecks ) and parallelized insert.pl script.

Thanks for the patch. It's a good idea, but then I realised you are
forking a process for every single service result that comes back,
which is not very efficient.
We've done this differently in 3.9.1 - we have a separate thread now
that handles the RRD updates, which can take as long as it likes (with
monitoring, of course). So this will stop the gaps appearing in the
graphs.
