I'd like to be alerted when my YSlow or PageSpeed rank goes lower then a threshold.

It's probably a good idea to compare the change over time instead of immediate value to avoid too much alerting.

From documentation I come to know it is tightly coupled with mySQL. Can we enable other Database support ?

Is there any special mySQL DB calls used ? Can we get rid of from special calls or syntax ?

All the websites with the best rated homepages shown in a top 100.

On the "Measurements Over Time" graph on the details page, there are several lines, all plotted against each other, which isn't really a useful way to visualize the data. One helpful possibility might be to separate/distinguish the lines that we want to go up (the scores) from the lines that we want to go down (pageload time, pagesize).

Say you want to test loading times in different geographical locations and tag your metrics with the location the measurements were submitted from.
The "tag" could come from YSlow/PageSpeed itself by allowing to (i) enter it manually or (ii) deducing it from the browser's settings (e.g. locale) or (iii) directly passed it from the script/automation tool that periodically instructs a browser to carry out the test and submit the data to ShowSlow.

I want to import some metrics from Google Analytics, e.g. bounce rate to be displayed next to my performance metrics to make it easier to convince my business to pay attention to performance.

It would be awesome if we could click on a header field such as page speed score or yslow grade, etc... and have it sort accordingly, descending/ascending

For the URL's that I monitor I'd love to be able to select a measure from each URL (say YSLOW gauge) and aggregate them on a single page - and make that publically viewable at a URL...

I would like to enter specific information on the timeline (something like a reminder - "r201 javascript optimization", "r307 removed google adsense" etc) Something ala google finance would fit perfectly

I want to write custom beacon and simple custom metric beacon is not enough for me.

In a continuous build (and functional testing) I might need to collect ranking data periodically. So it will be nice to generate a report (html, csv, xml) of the collected data in a period

..and allow the measurement graph to group by either the page name or the URL as it does now. Accept a cookie that can be used to store a user-definable page name. Users would set the value of the cookie with JavaScript. This would primarily be useful for internal ShowSlow instances, and the test URL uses AJAX to load page content dynamically, or any other case where multiple pages share the same URL.

I had a hard time setting up ShowSlow to use MySQL connection over a socket. The documentation page says it's an option, but the system is hardcoded to connect to MySQL on port 3306. Eventually I had to change the mysql_connect() calls to send a parameter for the socket path.

There is 10 times differences between an american accessing my site and an european one (yes my host sucks) : from 200ms to 2s ping.

If you can, we should be able to configure at least one location per url to test from

I wrote a blog about how to improve the performance of the All URLs page of ShowSlow. You can read more at thttp://bit.ly/bLRT8J. Maybe you are interested.Hope it is useful

Trying to do some differential analysis of a web server using Cnames, not working...

I have a domain, hvkørbæk.dk - it does not want to accept it in that format, or the IDN-format of http://xn--hvkrbk-tua5l.dk/

Well it accepts it, but i never get any stats

and format the timestamp, current one requires an effort to understand it : 2010-06-10T01:20:35-06:00
