Comment (by Thias):

 Unfortunately, this is a 32bit server, so switching to a 64bit OS isn't an
 It is a dual HT Xeon ("only" 512k cache per processor) with 2GB RAM and
 10k rpm 36G SCSI disks, and outputting ~70Mbps with varnish makes the load
 reach about... 0.5... so it should be able to handle quite a lot more.

 Could varnish be easily recompiled with large file support? E.g. adding
 -D_FILE_OFFSET_BITS=64 to the CFLAGS? RHEL4's Linux 2.6.9 can definitely
 support files larger than 2GB, I've actually created a 4GB file for
 varnish to use, but it couldn't and said :
 Error: (-sfile) "/var/lib/varnish/varnish_storage.bin"
 does not exist and could not be created
