I am working on a tiny little PHP project for a friend of mine, and I have a WAMP environment setup for local development. I remember the days when the response from my local Apache 2.2 was immediate. Alas, now that I got back from a long, long holiday, I find the responses from localhost painfully slow.
It takes around 5 seconds to get a 300B HTML page served out.
When I look at the task manager, the httpd processes (2) are using up 0% of the CPU and overall my computer is not under load (0-2% CPU usage).
Why is the latency so high? Is there any Apache setting that I could tweak to perhaps make its thread run with a higher priority or something? It seems like it's simply sleeping before it's serving out the response.

For me, setting the ServerName property in httpd.conf fixed the delays (they were up to 10 seconds at worst):# ServerName gives the name and port that the server uses to identify itself. # This can often be determined automatically, but we recommend you specify # it explicitly to prevent problems during startup. # # If your host doesn't have a registered DNS name, enter its IP address here. ServerName 127.0.0.1:80
I had the very same problem.
Setting localhost redirect to 127.0.0.1 in hosts file did not help. Optimizing MySQL server did not help (InnoDB -> MyISAM, changing many cache related directives in my.ini).
Then I used web webgrind and narrowed down the problem to "new PDO(...)" call. Changingmysql:host=localhost;dbname=dp-ui;charset=utf8
in dsn for PDO completely solved the problem! Page loading time went from over 3000 ms to 16ms.
However I am really confused why the "127.0.0.1 localhost" line in hosts file did not help.
The issue was with Apache's main settings file httpd.conf.
I found this:
There are three ways to set up PHP to work with Apache 2.x on Windows. You can run PHP as a handler, as a CGI, or under FastCGI. [Source]
And so I went into the Apache's settings and saw where the problem was: I had it set up as CGI, instead of loading it as a module. This caused php-cgi.exe to start up and shut down every time I made a request. This was slowing my localhost development down.
I changed the settings to load PHP as an Apache MODULE and now it all works perfectly. :)
To load the PHP module for Apache 2.x:
1) insert following lines into httpd.confLoadModule php5_module "c:/php/php5apache2.dll"AddHandler application/x-httpd-php .php
(p.s. change C:/php to your path. Also, change php5apache**.dll to your existing file name)
2) To limit PHP execution only for .php files, add this in httpd.conf:SetHandler application/x-httpd-php
3) set path of php.ini in httpd.conf (if after restart you get error, then remove this line again)PHPIniDir "C:/php"
Thank you all for your efforts.
Check if /etc/hosts is correct. Like this:# hostname mobrglnx1 added to /etc/hosts by anaconda 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ***** ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 *******
In the place **** give your hostname.
I had the same problem and finally discover that it was coming from two facts :I use Mac OS X MavericksI accessed my project via the URL http://myproject.local/ because I put a line 127.0.0.1 myproject.local in /etc/hosts
The problem appears because the .local tld is reserved for Bonjour service, and this since Mac OS X Lion (10.7).
Changing the tld for something else fixed the problem.
In your httpd.conf be sure to set the setting HostnameLookups Off.
In case it helps anyone, I had this problem and it boiled down to being incorrect DNS lookup.
The DNS Server on the server was set to 127.0.0.1 - I changed it to use the Google Public DNS servers, and that made it a whole heap faster.
The question has a tag apache-2.2, but if someone is affected by this nefarious issue also on WAMP with Apache 2.4 + PHP 5.5, the following answer on SO did the trick for me:
edit httpd.conf and disable the loading of the CGI module by commenting this line: LoadModule cgi_module modules/mod_cgi.sohttps://stackoverflow.com/a/18786773/260080
