Help! - Site Loads Very Slow
wordpress slow, site loading slow

I have a wordpress site that is getting average of about 23.5 second load time, per loads.in, Yslow and other tools tested.

Deactivated all plugins, removed header image and images from home page that I had in a gallery and still the same.

Have Super Cache plugin installed, wp-smush it plugin for image compression installed, and CSS is compressed as well.

loads.in shows 37 requests - 263.1 KB - for home page on loading.

Some are Adsense, one is a sidebar banner image served on my site, taking 377ms to load and others

The biggest load time wise seems to be wp-includes/js/jquery/jquery.js?ver=1.7.1 at 684ms

I've been working on this for 2 days and cannot find a solution, anyone can help? Or direct me to a forum that can help?

have you tried checking how things look in a waterfall chart?
you can do this using built-in developer tools in many browsers such as chrome and safari.
this should tell you which component is taking a long time and you'll see how much is latency and how much is load time.

i would also try things like nslookup and traceroute to make sure it's not a DNS resolution problem or network problem between you and the server.

Are you using extensionless URL's?

Read the last part of post #4274745 [webmasterworld.com] carefully. The "stock" rewrite reads the entire file system twice and I've seen **major** improvement on wordpress sites using this approach.

Also if you're on shared hosting, most of the time it's a remote mysql server - it could be either of those (shared or the extra connection to the mysql server.)

I've seen this before but it's quite often one of the following:

1) calls to offsite resources (like Google Analytics)
2) bloated database (run repair or optimize on it)
3) un-optimized images (especially if run in a slideshow)
4) big fat Javascript files loading into the header

A client site had an issue similar to this and I checked all of the above to no avail. For several months I banged my head but couldn't find anything. The the next WP upgrade came out and it also upgraded the the database. Voila. What was taking 20+ seconds to load came down to 4. I'm still not sure what it was but we're happy it's better now.

Here's a good site to test and they have a forum to discuss results:

this isn't always the case.
as far as i know, most modern OS, including linux, bsd, OS X, windows & IIS use a "filesystem buffer cache" so files that are often and/or recently accessed will be reaccessible almost immediately without a physical disk seek.
