A reading of _Mastering Regular Expressions_ leaves me with the impression that sometimes study() speeds things up but other times it just slows things down. So its actual behaviour on performance is likely dependant on your data, your regexes (which is also another sort of data) and then how often each data+regex combination is used. The way M_R_E leaves things, I'm not even sure you can arrive at any sort of truth by using benchmarks. Or... you can arrive at a local definition of truth only by testing your specific data + your specific regexes together.

The general idea is that a generalized benchmark for study() is invalid.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
