Description
Hello,
Did anybody test the performance of using PCRE2?
On Rocky 9, I have a loss of 30% when compiling with pcre2 (with pcre-jit & pcre-study). On Windows it's much slower as well (cannot measure it precisely).
Does somebody have different results?
Thanks
PS: could this be linked to https://github.com/SpiderLabs/ModSecurity/issues/2966 ?

Research direction
Start by reproducing the reported PCRE2 performance difference on Rocky 9 and Windows, including the pcre-jit and pcre-study settings. Compare the results with the alternative configuration and investigate whether the behavior relates to SpiderLabs/ModSecurity#2966; done means a documented, reproducible conclusion.
