h-tree for ext2

[Andre Nitschke <andre nitschke versanet de>]

Hello,
with tune2fs -O dir_index i activate the h-tree function for ext3 to improve
performance. now i am not interested in the journaling function, but the
journal makes the system a little bit slower. is it possible to use ext2 (also
ext3 - journal) with a h-tree index to improve the speed?
or must the filesystem be ext3 for these feature?
greetings

Andre
