Performance degrades with big databanks
When I load a big databank like 16000 strategies, it starts very well.
But as time goes load time becomes slower and slower.
Similar things happens when I perform WFM robustness test of a big amount of strategies.
For example 1200+ strategies.
GUI becomes very laggy.
CPU usage is high ~90%.
Memory usage is 16-18GB, total memory 64GB, free memory is available.
After more tests I discovered high disc usage during WFM automatic retest, is it OK?
Trying to fix these issues myself I enabled.
Automatic memory cleanup every 30 minutes.
But it doesn't make much difference.

Was running 930 strategies WFM test, completed 90% overnight.
Performance slowed a lot, got tired of waiting.
I stopped WFM test.
Even after stop, CPU usage is at 90%.
