oh ) nice Misha.kumar ...
The quartus contain many small files even i mark all as trusted software for antivirus. <- degraded perfomance with factor up to 2.
then virual memory used at fitter stage is quite big. <- is it enough , so you don't enlarge disk swap.
Accelarated launch and prioity changing on the fly with so called "Live optimizaton" software <- it creates troubles with quartus2
I wonder the time per stage in report file and actual real time -> for example 15 sec in report and 4 minutes in realtime.
