[dovecot-cvs] dovecot/src/lib-index/mbox mbox-index.c,1.45,1.46

Update of /home/cvs/dovecot/src/lib-index/mbox
In directory danu:/tmp/cvs-serv12327/src/lib-index/mbox

Modified Files:
	mbox-index.c 
Log Message:
mail_read_mmaped: Use mmap() instead of read() to read mail files. read()
seems to be a bit faster with my Linux/x86 and it's better with NFS, so
that's the default.
