This is very strange, We've seen reports of reiserfsck --rebuild-tree
of 500Gb volume (filled to 170Gb) finished in 8 hours.
Can you please verify that the read speed of your RAID5 is constant in all
the areas of disk, that it is not opearting in some kind of degraded mode
and is generally in good state?
What is the ARID5 hardware you are using?

Data is recoverable for sure, but the speed degradation you are seeing
is strange and I do not yet think it should be attributed to reiserfsck.
Bye,
