Check Out YSlow

Ted Patrick turned me on to YSlow, a Yahoo! Firefox add-on that integrates with Firebug to analyze web page loads and make performance recommendations. I’ve been using it for a few days now, and this one is very cool, check it out!

    Works well even for debugging the slow cfajax calls.

    YSlow was also mentioned on the High Scalbility Blog (and mine) about a month ago, and there is a great video presentation about it here (if my link gets through)…

    YSlow was a huge find for us. We implemented GZip from it’s recommendation and saw a dramatic change in the file size and bandwidth usage.

    I used it and now find that I cannot for the life of me get .cfm files to compress using the mod_deflate module in Apache 2. Everything else compresses so why can’t my cfm files? I couldn’t find any answers on google, only others who asked the same thing. One person said that it was a bug in mod_jrun but he was using CF 7.

    yslow has been a life saver for us as well. i have used it successfully for a variety of deployments and highly recommend it alongside Firebug for Mozilla Firefox. Great add-on to FF.
