Maximum number of proxy connections

Hello
I have three questions:
1. Does anyone have any experience from using Jigsaw as a proxy in a
large scale?

2. Is there any particular reason for the hard 200 concurrent TCP
connections ("on both ends") limit? You can't set it above 200 outgoing
OR ingoing in jigadmin... As I see it, it's dependent on the hardware
resources available (memory, CPU etc.) if you can manage more
connections.

3. Is the limit easy to change and recompile or does it involve changing
of jigadmin, jigadm etc.?

Best regards
