As before we are running on CP R77.30 hardware model is 13500 with cluster appliance with smooth and normal performance. But after upgrade to R80.10 all network performance to slow down, for example, we have PRTG monitor (network via checkpoint) have monitor our website performance, on R77.30 the loading time around 5x-1xx ms, after R80.10 drop to 5xx - 4xxxx ms. The second case is we have ping test under our core switch, the interface plug into Checkpoint firewall directly. The R77.30 ping time is below 5ms, after R80.10 over 1x - 5x ms.
I know that's very simple evidence and test result. But how to be next step? Hope I can get more advice, Tks guys
