Mmm... I guess Ill use ba_jail_devs_v1a3b full compile (HDR enabled[yes I know there's no HDR version on the server, this was used for testing when I got my i7 to see how well of a performance gain I would see with it])
Dual Core system:
Worst: Unoptimized: ~20 minutes
Best: Optimized: 10 minutes
Current i7 system: (This has 8 threads handling compiling vs 2 on the dual core)
Worst: Unoptimized: Someones TF2 map took like 8 minutes with 3000 Visportals
Best: Optimized: 1 minute and 45 seconds
Longest any map takes, optimized or not, cordon tools off or on.
Well executable_a1 takes 45 seconds full compile and HDR.
Every other map maybe like 2 seconds BSP only, 10 seconds w/ fast vvis, 30 seconds BSP & fast vvis/vrad compiles w/o HDR, 1 minute or so full compile with HDR.
Should never take longer than 20 minutes on a dual core system to fully compile a map (this does not take HDR into place however, 30 minutes is the longest compiling should take with HDR checked).
