“Tools of the trade” meeting was a good start!

Meeting last night was a good start!

Thanks to everyone who attended, I hope you enjoyed it.

I think it was important to see that front-end performance is a very important topic among the community, but still there are some topics of traditional back-end performance/load-testing/scalability/reliability that a worth have some events dedicated to; maybe we’ll even have some joint event with some operations meetup for those.

Next time I’ll also try not to forget my camera so I can share photos with you, but feel free to take and post yours. Also, if you’re going to blog about the event, please send links to the mailing list or the message board (even if your post is not favorable ;)).

We already have two events scheduled in June and July, but feel free to send me your suggestions regarding the topics you’d like to discuss or present at the meetup!

Once again, thank you to Nicholas Tang and Interactive One for hosting us and I’ll see you on our next meetup at Etsy (http://www.etsy.com/) on June 16th.

YSlow 2.0 and ShowSlow 0.2 with updated beacon

ShowSlow logo

Just a few days ago I wrote first version of ShowSlow and then released it Open Source.

But progress is unstoppable and Yahoo! released long-awaited YSlow 2.0 so it’s time for ShowSlow 0.2.

This means that I’m sitting down and analyzing Beacon parameters to make sure ShowSlow can collect data properly – so here’s the list of parameters that YSlow 2.0 is sending with the beacon (actual set of y* parameters depends on the profile used – ydefault sends them all):

Once again, to configure YSlow to send your data to a beacon, you need to set a couple configuration parameters on about:config page of your browser:

for YSlow 1.x

  • extensions.firebug.yslow.beaconUrl = http://www.showslow.com/beacon/yslow/
  • extensions.firebug.yslow.optinBeacon = true

for YSlow 2.x

  • extensions.firebug.yslow.beaconUrl = http://www.showslow.com/beacon/yslow/
  • extensions.firebug.yslow.optinBeacon = true

Where beacon URL is either public: http://www.showslow.com/beacon/yslow/ (your measurements will be shown to public so please make sure you’re OK with it before you use it) or private URL on your instance which you can get here: http://code.google.com/p/showslow/source/checkout.

OK, ShowSlow is taking shape and I decided to follow “Release Early, Release Often” motto so now it’s open source: http://code.google.com/p/showslow/

Current version accepts YSlow beacons and you can configure your browser to post to public showslow.com beacon or install your own instance if, for example, you want to hide the results from others.

New York Web Performance Meetup

After talking to Steve Souders about local events at Web2.0Expo in San Francisco, I realized that New York is missing Web Performance optimization event. I went ahead and saved 75% using Meetup.com discount code (Web2SF09 – graciously provided by Derek Odegard of Meetup team) and now you’re welcome to join New York Web Performance Workshop meetup.

Our first even is planned for May 12 and I’m looking for location at the moment, talking to a few companies I had preliminary OK from. In the first part of the event, we’re going to talk about current state of tools for web performance analysis and optimization and in the second part we’re going to look at the real-life sites and what can be done to improve their performance.

Performance @ New York Web Standards Meetup

The New York Web Standards MeetupYesterday, I talked about Web Performance at New York Web Standards Meetup hosted by theMechanism.

Thanks to all attendees for coming to the presentation, I hope it was informative and worked as a call to action.

If you have any questions or need help with your performance optimization project, feel free to post your comments here or contact me directly if you want, I’ll be happy to help.

HTML Slides with meta-data embedded using RDFa are available here

If you’d like to watch more presentations on performance (already have about 30 of them), you can visit TechPresentations: http://www.techpresentations.org/Performance

Including a couple presentations about YSlow and related tools: http://www.techpresentations.org/YSlow

Once again, thank to all attending, asking interesting questions and volunteering for YSlow treatment ;)
