Hello Emmanuel,
thanks for your reply.

Hi,

Couldn't this latency come from dns lookups ?
If that's the case, I'd expect to see the delay at each request; I do my tests on a single machine and I see results with no delay, 3 secs delay, 9 secs delay and conn-timeout. If we have dns-reverse lookup delay I'd expect it to be a constant time during tests, and also we have dns cache on the servers, so it should (at least) happen just once and then the entry be cached locally and not asked to dns server.
Are you using some directives such as 'UseCanonicalName DNS', 'HostnameLookups On|double' or even hostnames in some 'VirtualHost' entries ?
None of them are set or set to 'Off'.

Regards,
Sandro
