Big cpu usage by plgSystemJFBCSystem::doTagReplacements

Hi there,

Doing an analysis of our server load (on a very very busy website), using newrelic.com, we found that the single most resource eater (using 24.49% of the CPU cycles), was the following: 24.49% plgSystemJFBCSystem::doTagReplacements

So, the question is: What does it do? Can we disable it?
If (as I suspect) creates html head tags, can we replace them with hardcoded tags in the template, so that we skim that 25% off our cpu usage?

Thank you

Hi there,

Thanks for the answer,

We did the upgrade on Friday. Since Friday none of the transaction traces has had any of your modules in above the 1% of cpu usage. So, I will consider that it is ok for now. I will let you know if (on my setup), it shows again at some point.

Thanks
