Title: RE: monitoring a very large number of channels
In both cases - what is your network configuration? That is one possible limitation
-- each channel access monitor uses 28 bytes (as I recall).
-- each tcp/ip packet has 64 bytes of overhead.
-- channel access buffers and optimizes packets between a server and a client to limit the impact of the tcp/ip overhead.
-- Jeff has performance numbers and test code so that you can run the tests on your hardware.
What archiver are you using? The channel archiver with the RTree index has been benchmarked to archive 10K channels per second on standard PC hardware. With some high end disks, you could improve this.

Subject: monitoring a very large number of channels
Hi,
I was wondering what the limiting factor is with regards to placing
monitors on a large number of channels. For example, how many channels
can camonitor or channel archiver watch?
Thank you,
Patrick
