Memory usage looks good, I noticed on my laptop with Linux with Pentium M 1,6GHz that having something like 200 channels connected
makes very big CPU usage, but what to expect if every channel was connected to one channel.

Anthony here describes that there is one thread for channel, so don't expect it will change.

The same as above.

I don't know XP so well, but if it only has problems with many threads for one application then consider running multiple FS
instances on one machine.
