I have a lot of subscriptions, of which don't appear to be up to date.

Some communities, I see hardly no comments, and the vote counters never go up.

My assumption is the instance hosting the community is completely overloaded.

My instance, has gigabit symmetrical internet, 128G of assigned ram, and an entire E5-2697a v4 processor allocated to it (16 cores, 32 threads)

The worker count is turned up, but, in terms of my instance, it is basically sitting "near" idle, with a load average of < 0.30

There- anyway to speed up federation other then the instances hosting the communities upgrading their servers?
