Isn't a high number of ticks per second desirable?

Given that it is a huge modpack there can be any sorts of issues causing reduced ticks per second.
Adding another mod to such a huge modpack can behave in many ways.

I can not reproduce this, do you have any evidence for this? You can use the spark profiler.

I did use spark profiler and will report some more evidence later but almost 30% of client ticks
