As Charles said, any decent Pentium should handle 100Mbit (given a really good NIC). Not so with VPN. 3DES is big processor hog. If you want 100MBit VPN you need a screaming CPU. I've seen 40 Mbit VPN thru a 1Ghz cpu and DDR memory.

A decent pentium class system should be capable of saturating a couple 100 MBit links. You will need to use "server class" PCI NIC's (like the DEC based cards using the tulip driver, or the 3COM 3C905...I've heard good things about the Intel based cards as well, but haven't tried them personally). You'll also want a good PCI chipset (hard to quantify without getting into lots of low-level hardware details). As a general rule of thumb, processing a packet takes a fairly fixed amount of CPU, so if your saturated 100 Mbits of traffic is lots of small packets, you'll need more CPU than if the traffic is mainly large packets for bulk transfers. I think anything over a P133/166 should work fine, and something like a P-2 or P-3 system with a BX chipset (or better...anything with a 100 MHz FSB) would give you quite a bit of headroom. -- Charles Steinkuehler [EMAIL PROTECTED] ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ------------------------------------------------------------------------ leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ------------------------------------------------------------------------ leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html
