Ah, thanks for that last remark, I'll keep it in mind for future testing.

However, I double-checked and while I thought I remembered that -Dusedevel implied -DDEBUGGING, it doesn't seem so*. Hence, the 5.11 I used for the above results was no debugging build. Sorry for the confusion!


* I did "./Configure -Dusedevel -de 2>&1 | grep -i debug" and "make -j3 | grep -i debug" without any mention of DEBUGGING.

    The -Dusedevel option to Configure just quiets the "WHOA THERE, is this a development version of perl" message that otherwise quits Configure.

    I verified my original benchmarks with non-debugging perls (I wasn't sure if my 5.10 had been debugging, and I missed to look at perl5.10.0 -V ;), it didn't change anything.

[hippo]: But as shmem says, CPAN has been in core since 5.004 so unless you are on a packaged system you probably have it installed already.
[Spenser]: It's a stripped down version on a NAS device.
[Spenser]: It's frustrating
[Spenser]: Perl 5.10.0
[Spenser]: It uses opkg to install software
[choroba]: 5.10.1 would be much better
[shmem]: there are so many ways thinkable to fix that situation, some feasible and some not, that I'm unable to give good advice.
[Spenser]: I installed 5.22 with opkg. I can use it with cpan. I'm actually trying to install perl-DBD-mysql, but couldn't with it. So I went back to the factory version, 5.10.
