 |
|
I've just committed some improvements to my XML parser: TeqXMLReader. I was able to shave off 25? of the runtime in the first round. (The DMD profiler was a big help.) It's pretty fast, but I'm not satisfied. I think in the same league as the good Java parsers, and it bothers me that I'm lagging behind the Perl one. According to my tests, my parser takes about 25? longer than the Perl one to parse the same file:
| Code: | time ./timedXmlRead big.xml
Total time: 14782
real 0m14.786s
user 0m12.633s
sys 0m1.696s
time ./perlXmlRead.pl big.xml
real 0m12.343s
user 0m10.761s
sys 0m0.892s

I think the problem lies in the amount of system CPU time, but I'm not certain why.
I'd appreciate it if anyone interested would give it a look-see. I know that there are faster ways to do a lot of the things I'm doing, but I'm not seeing it right now.
Thanks,
John Demme |
