I'm glad you found this. I was going to build a new gcc and friends this afternoon. Looks like that's it. I'm seeing a 5-fold difference in reported usage between the 32-bit and 64-bit boxes for perl and CPAN shell. Haven't seen any httpd's killed off but the box has 4 Gigs and a light load. The 25% figure is what I had expected based on http://gcc.fyxm.net/summit/2003/Porting%20gcc%20to%20the%20amd64.pdf > > -- > Joe Schaefer > > -- > Report problems: http://perl.apache.org/bugs/ > Mail list info: http://perl.apache.org/maillist/modperl.html > List etiquette: http://perl.apache.org/maillist/email-etiquette.html > *****CONFIDENTIALITY NOTICE***** This e-mail and any files or attachments may contain confidential and privileged information.
