We use mod_gearman pnp worker to write the perfdata on a centeral server. This central server is a VM.This server is handling writing rrds for over 20000 checks with rrdcached. To further increase the performance we increased the number of rrdcached threads from 4 to 8 which helped.
Now to further increase the performance should we consider using RRDs perl modules using 'use_RRDs = 1' in 'process_perfdata.cfg' ? It seems I will need to update the rrdtool and install rrdtool-perl module.

Please suggest.

I'm not sure what the outcome of this would be, I would suggest checking their site to verify what this option could do in your environment:
