[Catalyst] Slow Makefile.PL

[Peter Edwards]

Wow, is that on an NFS-mounted partition or something? Something is very
wrong.
Cheers, Peter

Hi all,

I'm not sure what I did, but recently, my "perl Makefile.PL" run time
dropped from 4 minutes down to about 40 seconds.  The latter still seems
rather slow. A generic Makefile.PL on my box (generated with
"catalyst.plMyApp") takes about 1.5 seconds to run.

The slowdown appears to be when the Makefile.PL hits the "catalyst;" line.
 Devel::NYTProf shows it's I/O slowing things down (sorry for the rubbish
formatting):

Does this look familiar to anyone?  You can see right away that
File::Copy::CORE::sysread is taking 20 seconds.  Is a total runtime of 40
seconds a *normal* response time on running Makefile.PL?  This is a
relatively new project and I'm often rebuilding from scratch. That extra 40
seconds seems like a lot.  This is perl 5.10.1 (OS X Snow Leopard) and there
are currently only 36 .pm files in the lib/ directory.

Cheers,
Ovid
