Just some background info on the "250" number. I don't think we've done any scientific testing on how well OpenVPN performs with many users, so I'm really happy to see that happening. Having this said, I've heard over the many years I've been paying attention to this mailing list and #openvpn that people have been taken quite some performance when passing between 150-250 clients. The threshold isn't static, as it have looked like it is very load determined. A couple of things to watch out for: * What happens when 150+ clients do transfer a lot of data in parallel? * What happens when 150+ clients begins to renegotiate new session keys? I have no doubt that OpenVPN will tackle relatively many simultaneously idle or low-traffic clients. But once all of them begin to push a lot of data over the tunnel, then I believe you may see that the performance begins to drop. And especially when key renegotiation hits, as that is far more CPU intensive. - -- kind regards, David Sommerseth -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEARECAAYFAlSJV2AACgkQDC186MBRfrqbBQCeN4k0k+e+ALMfnDXvaKhUVfI5 Hh4AnjMP9OLIYSZwsQzFzVmoSKtuv1DK =eYtI -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
