v15 to v16 - Huge latency issues now

I run an SG135 at home. I've been running v15 for almost a year. I saved my config, ran the v16 hardware installer, imported my config and began noticing high latency at random times thorughout the day. Mostly late night. I never experienced these issues in v15. For no good reason, I would get 400-800ms delays to the Internet. If I reset the "Web Filter" service, it would correct itself  for a couple of minutes and then return to the same high latency. I'm not seeing anything odd trigger in the logs. No high bandwidth consumption at all. After a period of time, upwards of an hour or two of this behavior, the latency would quit and go back to normal. I decided to bite the bullet, pull a fresh copy of the installer down, reinstalled v16 from scratch and started a new config from scratch. I used default policies to apply to my interfaces, and the issues are back. I am at a complete loss. Has anyone seen this before? Thanks.

  • Derek,

    how is the ping from the XG itself? I mean, connect to XG and use the CLI

    Thanks

  • Hi,

    To investigate this further,verify the bandwidth received on XG through advance shell by downloading a file from wget command.Next,go to device console and run the command

    System diagnostics utilities bandwidth-monitor while running the game.Monitor if the bandwidth from the ISP's capped.

    You can always configure traffic shaping to limit the bandwidth usage for gaming websites and applications.Also,do you have IPS policy applied on the rule which can cut 20-25% of throughput during heavy traffic? As all the packets are deep scanned through the IPS engine.
