Buy a sata III card and put your lib on raid 0 of 2 x ssd 

What disk do you have ?

If you are not convince that ssd will fix you load problem, try to find a solution 

He has only one computer ! you cannot have an network bottleneck !

Hope this guy did the minimum check :

- disable WIFI, Bluetooth

- set his preload buffer to maximum

- set its DAW with large buffers and it's I/O buffersize to maximum (1024)

If not he should give us all the values he set !

Correct, no network.. single machine. And the CPU problem is sporadic like I said. Sometimes it's at 10%. Other times, I'll open the same project and it connects to VE Pro and then the CPU says 45-60%. Doesn't make any sense.

I'm not using the VST3 version. Digital Performer doesn't currently support VST3.

Please report all settings

Hi Charlie

You disable all non needed (Wifi, Bluetooth, Flash ......)

To see if you have enough CPU power and enough fast disk you should set all pre-load buffer size to maximum (in you DAW and in VSL)  

Is there are no more problems, you can start to reduce them until you get problems ! and set it back to the values where there is no problem.

Then if the latency is not acceptable, you should go with SSD and/or put memory to  32 or 48 GB, and/or change computer, and/or add slaves

For Kontakt it is the same, also it is better to have Kontakt in the DAW, if you put it in VEP you will add another layer in the processing.

Thats why I bought the new mac pro 3.5ghz 6core with 64 gig of ram and 4 1gig ssds,

Should have just bought a cheap pc 

That [Sam's] computer is very comparable to mine, and I get on pretty well. Without worrying about all of this theory, without SSD, without RAID. I actually do music all day with relatively few hiccups. I do not think the things Cyril is saying are it. For instance, the preload buffer for Vienna is by default high enough.

So, first things first: are you having trouble with performance or just trouble with something you see in activity monitor? I have seen things that don't even add up in it, for instance.

The symptoms of actual troubles will be more indicative of problems I think.

Can you give the figure in Activity monitor/memory after you had "stuttering and skipping."  

Put 8 core in VEPRO setting and Pre-load buffer to normal  in Directory Manager

Put DP with 1024 and test if it is playing ok, if not put pre-load buffer to bigger (you must re-launch VSL each time you change a parameter)

see : You disable all non needed (Wifi, Bluetooth, Flash ......)

Reboot, do not lauch any softare, only VSL and DAW

higher than 100% for an application just means that more than one core is being used.
