Yes I noticed that IB backfills are faster before market open and after market close.
I think that they prioritize traffic so order flow and streaming updates take precedence, which is actually good thing.

I updated today, but these problems have been occuring for over a week. I think IB is doing something to slow the data down because they are afraid their system may get overloaded by volume, but this is just speculation on my part. I say this because the backfill seems to operate much better after the market closes.

Although performance of single backfill is strictly dependent on TWS delivering
the data, I just ask you to make sure you are using latest version of the plugin (1.8.0)

Anyone having problems with IB backfills on futures. I am requesting a 5 day backfill and it is excruciatingly slow.
