Unscientifically, Lord of the Rings Online takes the longest to load on my system of any MMO. It seems I am not alone. One big problem is the fragmentation of the internal file system. Turbine just released a beta internal defragger for Lord of the Rings Online. Read all the warnings and problems to be safe, but apart from using SSD or a large USB drive to load the MMO, this should help speed things up.

handy dandy
Reminds me of the procedures to shrink Guild Wars’ GW.dat back to normal size. :)
I find that I always have to defrag my hard drive after a LOTRO patch, so I guess it stands to reason that the actual game files would have similar problems.
