Hi

Sonar 8.5
Windows 7 64bit
20gb ram
DualXeon 3000 mhz (8 cores)
Opus 1 & 2
Vienna Instruments (Many libraries)



What would be the best distribution of Kontakt instruments and instances of Kontakt to minimize the CPU load, if there are 30 average size instruments?

30 instruments in 1 instance of kontakt (Some instr are layer on same ch)
10 instruments in 3 instances of kontakt
6 instruments in 5 instances of kontakt


Also related to CPU.
Is it the number of midi channels or the number of instruments in an instance of kontakt that taxes the CPU?



Also, would purging samples, setting the proload buffer high and limiting the number of voices help the CPU load?


Thank you
