Rendering performance optimization

   Most of us are familiar with CPU consuming problem in Flash applications. There are cases, when you have nothing to do with, but in few cases you can use well known solution – cacheAsBitmap. It prevents object re-rendering in case a shape and content are never changed.



  There is a case when caching of Sprite object doesn't always solve the problem. What if your sprite contains different types of elements and all elements are static (no shape or position changes)? Does caching as bitmap of the Sprite will help to improve object rendering performance? The answer is yes, but there is a little nuance.

Tomcat Performance

Greetings,

 

I'm currently consulting at a client site where Tomcat is used along with Apache via mod_jk, and from time to time simple requests (=>ping.jsp, which just prints out "OK") take as long as 10-15 secs.

 

Has anyone ever tried to analyze the thread/request ratio automatically (this is a production site and we need constant monitoring)?

 

Is mod_proxy considered a better alternative for mod_jk for long http connections?

 

cheers,

z

Benchmark comparing caching options for Django

 This nice benchmark compares simple caching solutions for Django, either integrated or front-end, which provide amazing performance boost:

http://www.codysoyland.com/2010/jan/17/evaluating-django-caching-options/

 

Note that their all very simple to use (usually transparent to the application) & enable a x250 boost in response time & throughput.

Dumber is Faster with Large Data Sets (and Disk Seeks)

Jeremy_Zawodny describes his experience of filtering database data in code instead of SQL and how it made it run 12 times faster than the SQL version. (Note that he was Yahoo's MySQL guru)

Using declerative forms (in this case SQL) is usually deemed better since it lets the container (the database) process it in a much better way (since people writing the database are supposedly much better at finding out how to do things optimally). In this case, the result is the opposite

Performance testing open source JMS part 1

Matt Brasier, a consultant with niche Java EE consultancy C2B2 Consulting, compares the performance of JBoss Messaging, JBoss MQ and Sun Java System Message Queue, in their out of the box configurations. This first article looks at the performance of these three implementations when sending messages to a JMS queue. The results indicate that the overhead of establishing a connection to a server, and looking up a queue is lowest in JBoss MQ, but that JBoss Messaging is the fastest at actually sending a message.
