simplejson 2.0.1. Python’s simplejson JSON library got a whole lot faster while I wasn’t looking.
Dromaeo: JavaScript Performance Testing (via) This is one classy benchmark. Run it in as many browsers as you like (each run is saved to the server and assigned a run ID), then compare the results by appending ?id=[run1],[run2]... to the URL.
TraceMonkey. Brendan Eich has been preaching the performance benefits of tracing and JIT for JavaScript on the conference circuit for at least a year, and the results from the first effort to be merged in to Mozilla core are indeed pretty astounding.
ZeroMQ. Open source message queue optimised for performance: claims 25μsec latency and 2.6 million messages per second.
SquirrelFish. WebKit’s JavaScript engine was no slouch, but that hasn’t stopped them from replacing it with a brand new “register-based, direct-threaded, high-level bytecode engine, with a sliding register window calling convention”. It runs 1.6x faster and has the Best Logo Ever.
Yahoo!’s Latest Performance Breakthroughs. 20 new performance tips to join the previously published 14. Flushing the buffer while the backend code is still working to cause the browser to start loading CSS earlier is interesting.
IE8 speeds things up. Steve Souders notes that IE8 downloads script files in parallel before executing them sequentially, giving it a significant speed boost over other browsers that download sequentially.
Nginx and Memcached, a 400% boost! Ilya Grigorik wrote up my current favourite nginx trick—you set nginx to check memcached for a cache entry matching the current URL on every hit, then invalidate your cache by pushing a new cache record straight in to memcached from your application server.
"Why doesn't jQuery have an XPath CSS Selector implementation?" For now, my answer is: I don't want two selector implementations - it makes the code base significantly harder to maintain, increases the number of possible cross-browser bugs, and drastically increases the filesize of the resulting download.
Announcing StaticGenerator for Django. Simple but powerful static file generator for Django applications—just tell it about your model instances and it will create an entire static site based on calling get_absolute_url() on each one. Uses signals to repopulate the cache when a model changes.
20,000 Reasons Why Comet Scales. Greg Wilkins coaxes Jetty and Bayeux in to supporting 20,000 simultaneous users per server while maintaining sub-second latency, using Amazon EC2 to run the benchmark.
