6. VPN Performance

I did my VPN throughput testing using my Dell Inspiron 4100 notebook running WatchGuard's MUVPN client. My laptop's 10/100 Ethernet port running at 100Mbps full duplex was plugged into one of the 10/100 switch ports in my network's main router. The 6tcw's WAN port was plugged into another of the router's ports. Table 1 shows the test results.

This plot was taken with no other traffic active through the router, so the variation is probably due to coding issues. Checking Remote to Local throughput showed a similar profile.

I also ran a Chariot UDP streaming test (not shown) which didn't show similar variation. Qcheck tests at higher stream rates showed data loss starting at a stream rate a little below 800kbps.
