Which is the best OS for PPTP?
I installed PPTPD on both Redhat and ubuntu, and I found that the ubuntu is more slow than Redhat by testing, that is to say, Need I do some network optimization with Ubuntu?
We use FreeBSD as PPTP terminator because of fully in-kernel PPTP implementation, so it has no overhead for copying packets to and from userspace for en/decapsulation. Quad-core Xeon with hyperthreading handles near 400 users and 250Mbit of PPTP traffic in peak with load average near 2.5, but it needs good Intel network adapters to handle packets with low CPU usage.
