I don't think so. We are using size tiered compaction, not levelled
compaction, and there are only 76 SSTables for the entire keyspace (375
files currently in the directory).

Does your issue look similar this one?
It is also dealing with compactaion taking 10X longer in 1.0.X

I have been observing that major compaction can be incredibly slow in
Cassandra 1.0 and was curious the extent to which anybody else has noticed
similar behaviour. Essentially I believe the problem involves the
combination of wide rows and expiring columns.
