FortiClient causing slow load times for web pages

[#1]

Hello - I have FC v 3.0.599 (MR7) installed on about 40 workstations. We have a FortiMgr 100 (MR7) for managing these FC' s. I' ve noticed that since FC has been up and running that nearly everyone has experienced a change in web-page load times. Some pages are taking nearly 5 minutes to load. I can' t seem to pinpoint why this is going on - I do know that if I encounter a web page that is taking forever to load, I can shutdown FC and then re-visit the same web-page and it loads instantly. Has anyone else experienced this? Is there something I' m missing in the configurations of the FC' s that will improve this? Edit: I should also mention that the types of web-pages that seem to be problematic have some sort of submittable form. ex - It takes five minutes to update a web ticket on the FortiNet support site after you click the ' submit' button.

You are welcome. Log on to support web site and refresh your web page at the end of the day or tomorrow. I am not sure how fast the release people will be moving. :)

I was having some probems with forticlient. When webfilter enabled, network connecions became very unstable and with high load even causes the NIC to stop passing traffic. After some investigation, everything kept working fine when i used a different NIC (in my case the built in WLAN). The NIC causing trouble is a broadcom netxtreme gigabit adapter with the default (windows) drivers, 8.22.1.0 After changing some NIC settings in the advanced tab, it seems to work fine. TCP checksum offload > disable large send offload > disable

Looks like FortiClient did not process the offloading correctly. But pretty strange that I have a nVidia Gigabit NIC and have checksum and segmentation offloading enbled, it works fine.
