In the beginning, I had very bad performance not because Python was slow, but because my templates (Cheetah) was initialized in awake() method of Webware servlets. Later, I moved them to __init() method of each servlet. It helped a little, but it was not enough fast. When I moved them to external module (which is inherited by all my servlets) I gained the excelent performance. I was really surprised. It was even 20x faster than before. In the beginning, my memory was eaten up to 180 MB. Now it takes about 11 MB. I was working with PHP for many years. I was in development team od PHPLib and I know many tricks how to accelerate PHP. But, when I finally *correctly projected* Webware servlets, I was very suprised its good performance. It is far beyond PHP can reach. It is not only because Python is faster. It is mainly because Webware is the application server, and its servlets are compiled all the time in the memory. So I think, every application server (even writen in Java) can beat every non-trivial PHP application. PHP can be faster only for very simple code. But for more compilated code, when it have to load different modules and template files, Webware as application server is invincible. I did some comparision tests using ApacheBench http://codeflux.com/ab/ for my site and two others with similiar functions. (A) http://muratordom.pl/bank (Webware) vs. (B) http://www.pkt.pl/ (PHP) vs. (C) http://www.panoramafirm.com.pl/ (PHP) For max settings (25 request with concurrency level=5) the test for Webware (site A) was finished in 5.2 seconds. For site B in almost 30 s. and for site C in 13.4 s. The application A was 2.4 times faster than B and 5.7 times faster than C in total request time.

My Webware application (using much slower hardware and using many request from over 10 other projects, phpBB forums etc) has beaten modern, dedicated server with mod_php4 and compiled Smarty templates. In this situation Webware was still 20% faster. Python code combined with Cheetah is much cleaner and powerfull than every PHP code. Using Webware it is much faster than similiar PHP solutions. I am going to never go back to PHP again for non trivial projects. But I do not want to reject PHP, because it can be usefull for small projects or for such cute software as phpBB (http://www.phpbb.com). -- JZ ICQ:6712522 ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
