We have 4 HA sets of 200F firewalls. After upgrading to 7.0.13 we saw absolutely terrible SFTP/ FTPS speeds (2Mbps) over gigabit ISP, connected with 10Gbps copper SFP+. Also just straight 10 Gb fiber LAN traffic was 1.4 Mbps. Had to downgrade to 7.0.12 to return speeds back to normal. Our 10 Gig fiber is back to 8 Gbps steady. SFTP/FTPs traffic is running at 30MB/s now.
Fortinet troubleshot for 3 days before we pulled the plug and downgraded. HTTP(S) traffic was fine and speed tests in browsers were not showing issues.
7.0.13 has a directed bug fix for the 200F but it seems to have hurt more than helped. Just an FYI for anyone that may be having issues.
I tested in my lab for this case. It worked very well that sftp traffic was over 100Mbps. So, I want to retest with the same configuration. Can you share your sftp topology? Configuration? Or is there any special configuration related to this issue? If you don't mind, pls share the TAC ticket number, too. Thanks Regards
