500 symbols in a Portfolio Trader, with genetic optimization of (brute force ~400K) 29K simulations on a 3-moving average system won't finish

Grab any 500 symbols on a 10 years daily bars under a Portfolio Trader.
Stick a 3-moving average system and start a genetic optimization w/ ~30K simulations (brute force optimization would yield ~300K optimizations).
It's been running for 8h. I pressed cancel 6h ago, and it still carries on:

And it won't stop by its own if pressing cancel even if you leave it running for a full day. Behavior is consistent and repetitive, reboot is the only workaround.
