ShowSlow monitors your YSlow and Google Page Speed scores

Category: Performance

Show Slow has a great new feature. Sergey Chernyshev and team now monitor your YSlow and Page Speed stats:

Show Slow will fire YSlow and Page Speed at your site and collect statistics on a daily basis so you can just sit back and enjoy the graphs!

You can also check out the Alex 100 scores.

Steve Souders said:

Reassuring that the correlation coefficient of Alexa 100 YSlow and Page Speed scores is 0.83!

A very nice utility. Why wouldn’t you monitor your scores?

Is this feature also included in the hosted Showslow? that is neat!

Neat, but why would I use “facebook connect” ? What about OpenID ?

If you want to run this on your own server, it looks like it only works on Apache, http://www.showslow.org/Installation_and_configuration

@Marin – I answered on the mailing list (http://groups.google.com/group/showslow/browse_frm/thread/4d4cd67a4a751821), but I’ll repeat here – yes, you can do that on your own instance using scripts in the /automation/ folder.

@Yves – we use UserBase for registrations and stuff (another open source project of mine: http://code.google.com/p/userbase/) and I just didn’t have time to add OpenID, but I’m a big fan of it and will be adding it in the future.

@cancelbubble – it can run on any web server, it’s just that svn-assets needs some URL rewriting to make sure static content uses infinite expirations. There is a sample nginx config if you need it: http://code.google.com/p/svn-assets/source/browse/trunk/nginx.config_sample Other then that, Show Slow needs only PHP and MySQL.

YSlow has a silly bug which I reported to Exceptional Performance Group, yslow@yahoo-inc.com, Stoyan Stefanov’s e-mail and got zero replies. The only one who replied was Steve Souders, but unfortunately he doesn’t work on YSlow. So I stopped checking sites in YSlow in favor of PageSpeed.

@Yves – completely forgot that UserBase supports Google Friend Connect already so you can log in using many other credentials like OpenID, Google, Yahoo, Twitter and so on.

Just enabled it so you can use it: http://www.showslow.com/my.php
