See below. I hope MS Outlook does some decent indend so my response is clear -.-

All reasonably recent 32-bit OSs can address way more than 4GiB internally. For example: http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778%28v=vs.85%29.aspx#memory_limits This is generally done through PAE (http://en.wikipedia.org/wiki/Physical_Address_Extension) which allows 32-bit OSs to access more than 4GiB at the kernel level, though each process is still limited to 4GiB. Aha so I learned something new today :) I'm still puzzled as to how a 32 bit CPU can compute and fetch a memory cell with address above 4GB since it cannot hold this large value. Anyway that is just too much low-level computer science for me, all I ever had was a seven week course on architecture and networking (a single week out of the seven) :) -Casper Running a machine with more than 4GiB in 32-bit mode isn't stupid at all IMO. If you have relatively small processes, there's no need for the overhead of 64-bit even if you have 16GiB or more. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk7WbQYACgkQ9CaO5/Lv0PBsWwCgnifhHtqrLUBi7K4PeDjp4hnC JMkAn0gilsNy2hv3zu3nzUkrmrzxoYWF =AZpI -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
