Hi All, I use twisted as a flexible (authoritative) DNS server, and apart from its speed, I'm completely pleased with it. As you may know, Google has started a project -named unladen swallow- to improve python's performance, so I've taken a quick look at it, compiling the latest version (from svn trunk, which is based on python 2.6.1) on FreeBSD and compared the numbers with plain python's (2.6.2) performance.
As this is a DNS server, the performance indicator is queries per second. The numbers are here (in hungarian): http://suckit.blog.hu/2009/07/05/unladen_swallow The first table has the stock 2.6.2 python vs unladen python performance numbers (with an average of 3.5% speed increase), while the next table shows relative performance between unladen's -j whenhot and -j always settings (the first compiles code only when it's frequently executed, while the latter compiles everything at the first occurrence). -j always of course eats a lot of CPU power when compiling and also maintains a big memory footprint (712 MiB resident memory) throughout the process lifecycle. I hope the guys will be able to squeeze more out of python... -- http://suckit.blog.hu/ _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
