in thread Speed of 5.8.0 versus 5.6.1

samtregar,
Not that I doubt you, but I would be very much interested in hearing where you came across this so frequently that you chose "pretty much the accepted"? I typically don't care about speed at home (running 5.8), but really need it at work (5.6.1).

Cheers - L~R

    Around the time 5.8.0 came out there were threads on perl5-porters analyzing the performance of 5.8.0 relative to earlier releases. My foggy memory of the discussion features the "50%" figure prominently.

      The only performance issues that I'm aware of in 5.8 are:

      • The debugger can be a lot slower in 5.8. I think this has already been fixed in bleadperl.
      • There is a new hashing algorithm which may give worse behaviour in some circumstances. In general however it should give better performance.
      • The pervasive unicode support can slow things down (e.g. regexes on unicode are slower than regexes on ASCII) - but you can switch that off.

      There were, of course, a lot of performance enhancements in 5.8 too.

      So it comes down to what you do. Personally I've not noticed any performance difference.
