Hi. I've read through countless threads on here regarding Apache configuration and slow page loads but nothing I do seems to help.

My Linode 512 is hosting this Wordpress site: http://www.corstorphinehill.co.uk

It's not getting much traffic.

Sometimes, maybe every 15th page, it will take the page up to 40 seconds to load. It seems to spend a lot of time "waiting for website" in Firefox.

My YSlow score is Grade A (93/100)
My PageSpeed score is 95/100

I've ruled out my firewall (ufw) by temporarily disabling it. The load never seems to spike. I'm at a bit of a dead end. Can anyone please help? Is there any way to tell exactly why my browser is waiting?

Here's my apache config:

ServerRoot "/etc/apache2"

Been experimenting with KeepAlive on. Doesn't seem to help

I've tried reloading your site quite a few times and haven't noticed it loading slowly. Could it be network related? Try a ping -t and see if you're getting some slow pings or timeouts.

I loaded the site over 20 times too and no noticeable delay for me. Did you try using a different browser? One of the newer Firefox's did that to me with a website routinely. That why I still use 3.6

I loaded several times as well, it works fine for me.

And again from a different IP address . From my experience, I'd say your site is quite fine.

Thanks all for trying. I'm very reassured that nobody thinks it's slow!

I think the problem might only be evident if I'm logged in to Wordpress, although it seems OK today. I'll do some more experimenting.

Thanks again!

I don't know WordPress specifically, but it wouldn't be surprising if caching was largely or completely disabled for logged-in users.

Yip I'm pretty certain now that this is only happening when users are logged in. So this is a Wordpress problem rather than a configuration problem.

Thanks for everyone's help and input, it's appreciated

The page IS a bit heavy.

- front page has three 150kb images in the slideshow
- google analytics(13kb) and google pagespeed(54kb) and facebook js(43kb) loading in the head and 170kb of other facebook js loading later
- 3 web fonts

It looks nice, but it's not exactly built for speed.

Just to let you know, I loaded the front page a few times and I ended up getting a logged in page for DrookitMunter. I didn't actually have admin access, but you should check that you have your caching system properly configured, because it's caching admin users.

/category/blog/ seems to be the most likely page to lag.

These things are tough to track down. Unfortunately, the tools are pretty technical. xhprof for profiling, mysql slow query log and EXPLAIN if it's in the database query. I've heard good things about New Relic free trial.

You might want to go through your wordpress modules and research each one and see if others are having problems with any.

Thanks for the tips and thanks for warning me about the logged in as admin thing - worrying! I believe that's fixed now

Yeah http://corstorphinehill.co.uk/category/blog/ is slow for me.

Every refresh takes about 20 seconds.

It took a LONG time to load for me initially but then refreshing was just as fast as could be. The first load though was at least 30-45 seconds if not more.
