Re: [Boost-users] [Regex] Major performance difference between Boost.Regex and Linux regex library

Hi, I am just starting to use Boost.Regex, porting from the Linux system regex library to Boost.Regex, and after doing initial testing on my first change I see a major performance impact, where Boost.Regex is about 30 times slower than the system regex library.

The Boost.Regex documentation seems to imply that its performance has a positive comparsion with existing libraries so I expect that I am doing something wrong but can't see it. [lots of details]

Hi, it would be much easier to understand what you are doing if you could send your test program (compiling code, boiled down to the bare minimum). Regards, Roland
