Looks strange. For me FB1.5 CS on Red Hat is ~1.5 faster on both
backup and restore than IB6 or FB1 and is ~35min/4hours on 8Gb
database. Large part of restore time is creation of 2500 indices. Is
this the same hardware? Can't say what can be wrong with filesystem.
Perhaps heavy garbaged database? In this case -g option on backup
should help.
