it showing my cpu usage is 100% but it's not i just ran 50 threads on a 76 core 200gb server it seems now it is imposible to do much threads . i have truned off threads delay & and setup to open 300 threads on settings but it seems it still takes time to open new threads .
BAS says: Failed to start browser, not enough system resources. Free memory 175432 mb, processor usage 92 %
but on server usages, i see there is no spike
Export your spreadsheet as csv file, than import it to BAS as a resource and set it to use each line 1 time (it is default setting I think). That way each thread would take new line from your csv file in run mode or as compiled bot.
