Hi there,
Do some basic tests, like try the following from your haproxy vm to
your server:
ping -A -s 18000 -c 1000 -q 10.3.4.84
PING 10.3.4.84 (10.3.4.84) 18000(18028) bytes of data.
--- 10.3.4.84 ping statistics ---
1000 packets transmitted, 1000 received, 0% packet loss, time 1303ms
rtt min/
Reserving memory is critical especially if you over commit. Haproxy degrades
extremely quickly when things swap. Don't allow swapping inside or outside of
the vm. Reserving a small amount of CPU is good. That said I doubt if either
of these is your problem. It's probably more related to the
first you should reserve resources on your ESX server for your HAProxy
box, to ensure it will never wait for the hypervisor to find some
resources for it.
Then, in the VM, you should tune networking sysctl (tcp port range,
tcp rmem, wmem, the syn backlog, etc...)
you can also do CPU affinity per p
Hi,
In my case, I searched on my Debian server but I don't find nf_conntrack
...
Concerning tuning my whole system, why not but in which direction? :-)
Regards
Christophe

Sorry, but this is not possible as it requires the timeout to be elapse
