> we are using Sstable-Generation API and Sstable-Loader utility.As soon as
> newer version of cassandra releases I test them for sstable generation and
> loading for time taken by both the processes.Till cassandra 0.8.7 there is no
> significant change in time taken.But in all cassandra-1.0.x i have seen 3-4
> times degraded performance in generation and 2 times degraded performance in
> loading.Because of this we are not upgrading the cassandra to latest version
> as we are processing some TeraBytes of data everyday time taken is very
> important.
