Beyond filevalt, macbook(pro)s also have a pretty bad track record of trashing drives (after the intel changeover mac sleep writes RAM to disk before the drive spins down -- and before many users put their laptops in bags and start walking). This trashed drive can present as random long io blocking for weeks or months before the drive fails. http://discussions.apple.com/thread.jspa?threadID=960977start=0tstart=0 is an old thread about the issue. http://www.macworld.com/article/53471/2006/10/sleepmode.html is the fix I run my macs with -- one caveat is that if the computer runs completely out of battery it in effect does a hard boot.

[Catalyst] Slow Makefile.PL
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.pl MyApp) 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): Top 15 Subroutines — ordered by exclusive time Calls P F Exclusive Time Inclusive Time Subroutine 2556 1 2 20.0s 20.0s File::Copy::CORE:sysread (opcode) 1274 1 2 5.19s 5.19s File::Copy::CORE:syswrite (opcode) 2636 3 2 1.87s 1.87s File::Copy::CORE:close (opcode) 142 1 2 796ms 796ms Cwd::CORE:backtick (opcode) 2708 2 2 781ms 781ms File::Copy::CORE:open (opcode) 36 1 1 749ms 5.78s Module::AutoInstall::_load 2844 3 2 463ms 463ms File::Copy::Recursive::CORE:chmod (opcode) 26 2 2 303ms 303ms Module::Install::Admin::CORE:close (opcode) 1 1 1 208ms 214ms MooseX::Types::be...@11 1354 1 1 205ms 28.1s File::Copy::copy 14 1 2 181ms 181ms DynaLoader::dl_load_file (xsub) 72 2 1 172ms 236ms Module::Install::__ANON__[inc/Module/Install.pm:324] 1 1 1 155ms 254ms Module::Install::Admin::Metadata::dump_meta 28 1 1 155ms 2.52s Class::MOP::__ANON__[Class/MOP.pm:103] 5706 6 2 153ms 153ms File::Copy::Recursive::CORE:stat (opcode) 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.
