Re: Serious performance bug in Perl
I have missed a bit of the conversation here, so it isn't clear to me
which lib6 is being used.
I am currently preparing the 2.0.7 release version. To the best of my
knowledge the 2.0.7pre3 (in slink...sorry) had some major NIS work done on
it, but there isn't anything between then and now.
If 2.0.7pre3 isn't an improvement over pre1, then I need to know about it,
and what is causing it so I can complain upstream about it ;-)
Thanks,
