Hi, Thanks for the input guys, however the 15 second pause exists even if i explicitly disable reverse lookups in apache 'Hostnamelookups Off' in httpd.conf and my server is operating on an internal network in a company so although i cant say for sure i doubt there is much IPV6 stuff around.
Does anyone how how i would establish if there was a DNS related delay ? some tool that could test DNS and name lookup speeds ? i am a software guy trying to use SVN not a network guy regards Matthew J Fletcher > -----Original Message----- > From: Alan Buxey [mailto:a.l.m.bu...@lboro.ac.uk] > Sent: 26 April 2011 23:05 > To: openssl-users@openssl.org > Cc: Matthew Fletcher > Subject: Re: slow https conenctions > > Hi, > > On 04/26/11 3:06 AM, Matthew Fletcher wrote: > > > I've come to this list in search of help with slow https > conenctions (via the subversion, apache and finally mod_ssl lits). > > > > > > There is a 15 second ish delay whenever a client connects using > > > https, > > > > 15 seconds sounds to *me* like a DNS related timeout. perhaps the > > server is doing a reverse lookup on the client? > > ...or is getting a AAAA record, trying to connect to that > IPv6 address....and failing, then falling back to IPv4 > > alan > ********************************************************************** Serck Controls Ltd, Rowley Drive, Coventry, CV3 4FH, UK A company registered in England Reg.
