Summary : Perl extension for very fast parsing of VCards
|
Description :
Text::VCardFast is designed to parse VCards very quickly compared to pure-perl solutions. It has a perl and an XS version of the same API, accessible as vcard2hash_pp and vcard2hash_c, with the XS version being preferred.
Why would you care? We were writing the calendaring code for fastmail.fm, and it was taking over 6 seconds to draw respond to a request for calendar data, and the bulk was going to the perl middleware layer - and THAT profiled down to the vcard parser.
Two of us independently wrote better pure perl implementations, leading to about a 5 times speedup in each case. I figured it was worth checking if XS would be much better. Here\'s the benchmark on the v4 example from Wikipedia:
Benchmark: timing 10000 iterations of fastxs, pureperl, vcardasdata... fastxs: 0 wallclock secs ( 0.16 usr + 0.01 sys = 0.17 CPU) AATT 58823.53/s (n=10000) (warning: too few iterations for a reliable count) pureperl: 1 wallclock secs ( 1.04 usr + 0.00 sys = 1.04 CPU) AATT 9615.38/s (n=10000) vcardasdata: 8 wallclock secs ( 7.35 usr + 0.00 sys = 7.35 CPU) AATT 1360.54/s (n=10000)
(see bench.pl in the source tarball for the code)
