Run one after the other. cdnlayer to me is appalling - has been since jeremy started using it.

It looks like cachefly (cf.html) is consistently fastest or second fastest for the greatest number of people. I vote for that one.

jeremy 07-14-2009 11:24 AM

A quick update: I've not forgotten about this thread, I've just been doing a little more research. CacheFly does seem to be the fastest for many, but it's the only one that seems to exhibit the random delays/pauses (and I've experienced those firsthand). It's possible I'll start moving some items to CF so we can get a live real world comparison. Thanks and keep the feedback coming.

At 14:20LQST I updated many of the images to be served from CacheFly. With images from two CDN's being served on the same pages, it should be easier to tell if either is causing a lag. Feedback is appreciated.

As requested - rerun of the same script
Code:

cdnl.html
55.1927 +- 131.9 KB/s
cf.html
194.8 +- 26.5153 KB/s
front.html
56.5233 +- 1.81994 KB/s
local.html
65.55 +- 1.57912 KB/s

Immediate rerun similar (that stddev for cdn is a killer).
Last night (again) my browser stopped (for minutes) waiting on cdnlayer. Happens a couple of times a week.

I'd like to test one additional option before making a final decision. How does the following look for members?

Thanks for the patience.

Looks like a 400 Error :)

jeremy 09-09-2009 11:19 AM

The page definitely comes up OK for me. Are you getting the 400 error for the page (served by LQ) or the images (served by the CDN)? Is anyone else getting a 400 error? Have you tried a shift-refresh?

GrapefruiTgirl 09-09-2009 11:21 AM

Code:

                              400 Bad Request
________________________________________________________________________________
                                  nginx

That's something like I get. Tried shift-refresh, still the same.

(So to answer your Q, it's not the CDN, it's LQ generated AFAICT)

I'm on IE7 on WinXP via Citrix and that came up in under a second for me.

unSpawn 09-09-2009 11:23 AM

I noticed the CDN change before I read this post, the images look OK to me.

jeremy 09-09-2009 11:27 AM

GrapefruiTgirl, looking at the logs - you're either browsing through a very broken proxy, have a broken browser plugin installed or something similar.

I get 400 too, even after ctrl+refresh (which seems to be the shortcut for force-refresh on Windows, at least; shift-refresh had no discernible effect).

LOL.. Leave it to me to find something broken that isn't broken ;)

I'm not using any proxy that I know of. It could be my ISP??

As for plugins, as far as I can tell, all those I have installed, are as they should be. Any in particular I should be considering closely?

jeremy 09-09-2009 11:32 AM

I've installed a server workaround that may fix the issue. Can you try again?
