My "~/Maildir/.ML_devel.linux-kernel@vger_kernel_org/cur" has currently
153.000 messages with arround 3 GByte and even mutt open it localy in
less then 4 minutes without "hcache"

I am using ext3 and used "tune2fs" to add the "dir_index" which
increased the speed by faktor 6. I should note, that I am already using
a Raid-1 with two 74 GByte SCA drives plus Hotfix of 15.000 RpM.
