Multiple Instances

Is there really any point in running multiple instances of FAH on the same computer? One instance takes up 100% of the CPU, so adding another one isn't going to increase throughput, it will just spread the work around. And could there even be some performance decrease due to all the context switches between the two processes (not on a Hyper Threading machine)

On P4's with hyperthreading, 1 instance will only use 50% cpu usage, so in order to get the full use of the processor you have to run 2 instances. On anything else, it doesn't really accomplish anything.

Or disable H.T. and run 1 version. I like the high clock speed of the P4s and 2 versions, I have read it does produce more. Its not double but there is an increase in running 2 with P4s H.T. or 2 Cpus etc. like 25% if I remember correctly. I would have to do some searching on here or google but it supposedly does help.
