 Posted: Tue 20 Mar '12 18:29 Post subject: Apache 2.4 Slow local cross-site access in Chrome |
 |
|
I have the x64 version of Apache 2.4.1 running with several virtual hosts set up on my machine, including a local general-purpose "shared" site I use to host JQuery, Modernizr, other other commonly used files.
The problem is that occasionally Chrome will stall for about 10 seconds when loading these local cross-site scripts/styles, but eventually the page is loaded successfully. Other times Chrome will load the exact same page in under a second, even with the browser's cache disabled.
Firefox & IE do not have this issue. This quirk never occurs when serving the same page to Chrome with Apache 2.2, nor does it occur when the scripts & styles are moved to the same virtual host. If I try to load just a CSS file from another local site it causes Chrome to stall. error.log mentions nothing.
My httpd.conf is stock configuration outside of switching the base directory for Apache & enabling vhosts. The httpd-vhosts.conf pretty much looks like this:
| Code: | <Directory C:/site>
<RequireAll>
Require all granted
</RequireAll>
</Directory>
<VirtualHost *:80>
DocumentRoot "C:/site/shared/www"
ServerName shared
</VirtualHost>
<VirtualHost *:80>
DocumentRoot "C:/site/test/www"
ServerName test
</VirtualHost> |
Any help would be greatly appreciated. This problem has been driving me crazy. |

EnableMMAP off

| I think it is about the resolving of the DNS. I noticed that some browsers are struggle if they have to resolve as second or a third domain to additional content. You should try the network viewer tool in chrome and observe that. It is the old question: CDN or no CDN. Often you are faster without a CDN when the browser hits the page the first time. After that the CDN is faster... but that is just my experience |
