in reply to Which is the best compiler

Perl is not compiled, and there are no compilers for it, at least not for production use. Maybe, maybe, Nicholas Clarks When Perl is not Quite Fast Enough can be of help for you, but the first approach is always to optimize the program itself instead of looking for a different Perl interpreter!

Also consider buying a faster CPU or faster machine - it may be cheaper to buy bigger hardware than to look at the program and change it.

    While the degree of approximation of this answer does indeed make it an appropriate one to the question being asked, perl code is compiled, much in the same fashion in which Java code is compiled into bytecode. Just to be fussy...
