Site-to-Site OpenVPN Suddenly Slow?



  • Hello Folks,

    We have two pfSense 2.0.2 boxes running a Core i3-2100, 16GB of RAM, Intel NICs, and SSD drives. Each site is connected via a 100Mbps link, same datacenter provider so the traffic never touches the public Internet. All of a sudden our site-to-site VPN cannot break 800KB/sec or about 6Mbps. CPU usage stays below 1% while the max speed of 6Mbps is reached. Both sites can run a speedtest to speedtest.net and test around 80Mbps-90Mbps up and down.

    I've rebooted both pfSense boxes with no change. I've previously tested this at a solid 80Mbps.

    I'm testing by copying a 25GB files between two Windows servers.

    Could this be an issue with 2.0.2? Is there any way I can figure out why this is happening?



  • Anyone? This is killing a SQL replication project we're working on. I can't seem to figure out why this is suddenly happening.



  • without more information i doubt we can be of assistance

    I've opened a ticket with pfSense.

    It would have been helpful to state what additional information would have been helpful to you however.
