issue with 5.7 and 5.8

I noticed that while running RouterOS 5.7 or 5.8 on my x86 (P4/2.8 1GB ram) I suffer a lot of page load timeouts, and partial page loads (browser never ‘gives up’). Reverting back to 5.6 has worked in both cases. I have noticed CPU loads are much lower with 5.7 and 5.8 - but the 10% connection failure rate sours the deal.

It “feels” like a NAT issue - like a few requests get lost. I’ve seen no sign of packet loss on active connections, just an inability to initially set them up.

I could easily have something configured incorrectly causing the problem. If nobody else has seen a similar problem, I will attempt rebuilding the configuration on that router from scratch.

Thanks!

Rebuild.
