Noticeable TCP Performance drop 12.8.x


https://techsearch.watchguard.com/KB?type=Known Issues&SFDCID=kA16S0000007lO7SAI&lang=en_US

Is it possible to elaborate on what the problem is with the NXP LS10xx series running fireware 12.8?

    There's an issue with connection oriented TCP traffic traversing the firewall as quickly as expected on the 12.8.x versions -- UDP traffic isn't affected. This generally occurs when the CPU is busy on the firewall (so the firewall would generally need to be moving a lot of traffic for this to be noticeable.)

    If you're running into this issue, I'd suggest opening a case. The development team is working to fix the issue and optimize to prevent future issues.

    Thanks´s. Most of the heavy traffic (https) on my T20 devices are routed through my central device for scanning so they are usual not that busy. Hopefully that´s why i have not seen this issue.
