However, it is not a very fast solution. The idea of having case insensitivity in XFS is to bypass that complexity in samba and let XFS handle it. The current thinking of the samba team is that this will improve samba performance as much as 15-20%. - bones -----Original Message----- From: linux-xfs-bounce@oss.sgi.com [mailto:linux-xfs-bounce@oss.sgi.com]On Behalf Of Andi Kleen Sent: Friday, May 23, 2003 9:03 AM To: Keith Owens Cc: Andi Kleen; linux-xfs@oss.sgi.com Subject: Re: Mixed case support in XFS > Easily handled with a tweak to locasefs. creat() and readdir() > preserve case, stat() and open() on existing files drop the filenames > to lower case.

AFAIK samba does it already internally, but the algorithms they use for this (which are more accurate than your hack) are relatively costly, so they prefer to get file system support. -Andi
