Hi,
I'm encountering a real problem with lastest Debian squeeze kernel. With 2.6.32-31 kernel (Debian Squeeze 6.0.2) all is working OK. When upgrading to Debian 6.0.3, LVS NAT started to be very slow. A single html page, 4KB, takes about 10-15 seconds to display (immediate on 2.6.32-31). We tried with 2.6.32-38 and lastest 2.6.32-39, we have the problem with both. We tried to upgrade only the kernel from 6.0.2, so we are sure this is related to the kernel. If we access the real server directly, there's no problem, and his IP Gateway is on the load balancer, so the IP forwardind seems to work correctly on the server. We tried with keepalived 1.1.20 and 1.2.2, It seems it's not related to keepalived. So, It must be NAT from IPVS layer. The only modified kernel values are ipv6 disabling (tried with and without, same problem), and ipv4 forwarding. We recompiled ipvsadm-1.26 (1.25 by default on Debian), and recompiled keepalived 1.2.2 on the platform with correct kernel headers, rebooted, same problem. Has someone the same problem?
