Hi everyone.
For some reason the initial connection to a resource (.js, .php, .html - whatever it may be) is extremely slow.
The server is Apache/2.4.4 (Win64) with PHP/5.4.4-Win64 running on Windows Server 2008 R2. There is also an x64 version of MySQL 5.6.11.
I don't believe MySQL or PHP themselves are related to the issue as the same thing happens with static html files as well.
For example, I made a request to http://servername/index.php and it took 20.10s for the server to return a response. Subsequent requests are fast, until such time that, presumably, it needs to create a new connection.
It's worth mentioning that I'm the only one using it at the moment (so no server load) and its only being accessed over an intranet (pinging the server results in a response < 1 ms)
I am trying to replace a server running on my local x86 XP machine which works without issue.
Anyway, I don't even know where to begin looking for the cause. Any thoughts?
Thanks! |

Do you have in your httpd.conf:
AcceptFilter http none
AcceptFilter https none
EnableSendfile off
EnableMMAP off
Same when you use the IP or 127.0.0.1 instead of servername ?
Using network folder somewhere in your httpd.conf ? |

Of the four variables you mentioned, "EnableMMAP off" is the only one I have in my httpd.conf file (which I just set earlier today to see if it fixed the issue - but it's had no impact). I also don't believe the SSPI stuff (see below) is causing it either - the problem existed before that was added.
I get the same speed issue whether I use the IP or the servername, and no, it's not using any network folders.
BUT - I did come across a new piece of information that will hopefully help. The server is on my work network - which is where I would have accessed it in the past and experienced the issue. This time I accessed the server from home over VPN and I'm having no delay issues at all - so it seems to be isolated to the internal network.
If it helps, here is my current httpd.conf file (with commented lines removed):

Steffen,
from the couple of pages I've tried, that change appears to have solved the issue. However, I won't know for certain until I do more testing
Any idea why that might make a difference on this particular server and not the other one I'm running? Or why it doesn't seem to affect it when I connect via VPN as opposed to directly from on the network? |
