I'm testing an intraday strategy which I usually test by running each backtest over a monthly period (I have two backtest nodes, so two months at a time). Usually it takes 7~9 hours per backtest, although over the past few days my backtests are only at 60% and 80% over 24 hours. This started happening a few days ago, I tried killing and restarting the backtests but they are still taking much longer than expected. Is there something going on with QuantConnect that would cause this slowdown? Thanks.

Issue seems to be slightly different actually… I've run it a few times and it always seems to stop at the same point (about 3-4 weeks in out of 1 month). Still not really sure why though, as it was working fine less than a week ago. It doesn't time out (e.g., 10 minutes on one loop) either, it just doesn't output anything and doesn't advance after hours. Any ideas on what type of diagnostics I could run to get this working again (maybe it's running low on RAM the longer it runs, I don't save/store anything between days though)?
Edit: I can run the days that it seems to be stalling on one at-a-time, but it only hangs when starting things from the beginning of the month

Yes, backtests are definitely far slower over the last few days. I had stuff that was completing in 5 mins take 30 or more.Â
