( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Thnx for the great info. I went stomping around the 5.8.7 source, and located the TlsAlloc() call (in the ALLOC_THREAD_KEY macro), but can't find more than a couple instances of ALLOC_THREAD_KEY being called...probably requires a hard-core debug effort to track down why/where so many are needed. (Unless any of the p5p'ers out there might shed some light ?)

I also googled about to see if I could find a registry key to tweak Win32's limit, but wo/ luck, it appears to be a hardcoded value.

Which is a bit puzzling, given Win32's preference for threading vs. forking. Considering that dual core CPU laptops are now available, and both AMD and Intel have announced quadcores for next year, I'd hope hardcoding this value might need re-examination, if they intend to play in the high end server market. (And the constant's name seems backwards: TLS_MINIMUM_AVAILABLE actually means the maximum available). Guess I'll have to wait and see what Vista brings.

I guess one can point fingers of shame at both Perl and Win32. Fortunately, 120 threads is sufficient for my needs on Win32 at present.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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.
