in thread Speed of 5.8.0 versus 5.6.1

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.

[choroba]: Yeah, let's ban dot in INC, but add glob to it!
[Corion]: choroba: Well, at least the above is user-defined, not implicitly by Perl ;)
LanX globalization is evil! Lets Perlxit!
