I've been looking at my /proc/sys/kernel and vm dirs on a fedora core 2
box with:
2.6.10 Custom Linux Kernel with glibc 2.3.x
2 x 2.4GHZ opteron64 (250) processor
8Gb 400MHZ DDR RAM (8 dimms)
2 x Adaptec SATA RAID controller
2 x 1TB SATA RAID drives with ext3 filesystem
1 x 8GB Seagate internal IDE drive with ext3 filesystem.
18GB total swap across all drives.

My issue is that I'd like to know how linux deals with large files
(greater than 10GB). Is there a way to control how large of a file can
be placed into memory? Or some tuning parameter to play with large
file capabilites? I've looked at sysctl as well and although there is
information available concerning HugePages etc..., I'd liek to know of
any docs that delat specifically with Large File handling on linux.
Thank you
