Google Site Speed has reported no major changes in the page speed characteristics of the site recently.
I will see what can be done to get things improved - right now we have a very high Page Speed - 96 / 100, we use Amazon's CDN for all static content, and I don't see too much room for improvement on the current hardware / software combo. I'll do some housekeeping and reboot the machine (it's been up for a year) and see if it blows any cobwebs out of the system.

I nearly posted something last night about this...
I've noticed this slowdown at times and can confirm that when this happens (such as last night) that if I sit and watch (and refresh) the main index to see the latest threads, I find that the notifications to threads I am subscribed to slow down too. Normally a notification is received within seconds of a post going live but when the slowdown occurs the notifications were taking up to 5 minutes to appear in my inbox.
Don't know if that helps or is significant or not.

Hi Mooly..Mooly said:
I have also noticed the site is a LITTLE BIT SLOW and i have scripts DISABLED so its probably faster for me than it is for you.... Try Disabling "Active Scripting" and you should see a big improvement on the site.......
Alot of sites I am on have been having all kinds of issues the last few days,very strange stuff going on!
another reporting slow behaviour...response has dropped considerably over the last month, but the last week has been almost unusable...I've dropped in casually a few times to have a look and then steered away after a long wait without getting any response......by long wait I mean a minute or two.....must be at the impatient age.

I find that when I'm getting really cruddy response, it helps a lot to disable javascript in the browser.
Particularly annoying is when my browser's "hanging", and the status bar tells me it's waiting for googleads, googleanalytics or daststic.com. Sometimes I can view the page source and see that the entire page has loaded, right down to the </html> tag, but the dang browser won't render anything because it's still waiting for something I don't care about and never comes. Then I switch off javascript, refresh the page and it comes up in a jiffy.
Maybe it's time to update my software too - still using Firefox 3.

The server is definitely (confirmed) experiencing intermittent slow downs, caused by the CPU usage spiking. One minute it's fine, 5 minutes later it's overwhelmed. It appears to be database related. Over the next week I'll be doing various things to try and find the culprit. Sorry for the inconvenience.
We have been making methodical changes to the server to address the occasional performance issues experienced over the last month. So far progress has been good, server load is now back to levels pre-April, we are continuing to make improvements over time. Thanks for your patience.
(Please note this is a dual quad core server, so server load should always be under 8 to avoid process traffic jams)

Hi Andrew, I assume the google analytics is to do with the advertising engines... dastatic is one of Jason's domains. Could be for the images on the site, though I'm not sure of that, as I had to allow javascript from that domain for something to work properly (but can't remember what it was, possibly the menus along the top of the screen)...

The Google analytics code is asyncronous meaning it works in the background and does not (should not) delay page loading.
Static image content (images that do not change / are not dynamic) is, arguably, best loaded from a domain other that the cookie laden primary domain of a website (we use dastatic.com, as opposed to the main domain of diyaudio.com). This is best practice to make things ever so slightly faster.
Cookies would normally be included in all the request headers for a website. On a typical website with a few hundred images on the page, that's a lot of extra data. Using an independent domain, which has no cookies at all, results in a few less byes being sent per request. While you'll find if you're using a modern browser, most small images on diyAudio are actually embedded in the HTML to save requests using the "url:data;base64" format, there are still plenty too large to use that embedded format and they were possible should be coming from datstatic. Or from Amazon Cloudfront via cdn(x).diyaudio.com.
FWIW: Javascript is a resources burner, specially because it can be called from somewhere else and bring poorly coded script.
Yet disabling all of it at once makes for incomplete or impossible navigation.
I use the NoScript add on for Firefox, which lets me choose.
Just now, I'm navigating this page with no problems at all.
Enabled: google.com , diyaudio.com , dastatic.com
Blocked: google-analytics.com , googlesyndication.com .
Works like a charm
Try it
when my screen hangs waiting for a response from DIY audio, I see in the bottom left corner
waiting for dastatic, or waiting for google, or javascript.
There are many others but they are not nearly as frequent.
But the sum of all these "waits" is a long delay in loading a page.
While the page is still loading I can scroll to a section, but as soom as the next piece of info has finished loads the scroll returns to the bottom of the page. If I scroll again the same reset happens.
It's better to wait for all the "waits" to complete and then scroll back through the two or three new posts. BUT that can be a long WAIT.
