We would be very very interested in your results. We currently run 10M but have heard of 256M sizes as well.
Please let us know what you find out.

In test, we've been trying to verify that the sstable file sizes change and then doing a bit of benchmarking. However when we run alter the column family and then run "nodetool upgradesstables -a keyspace columnfamily," the files in the data directory have been re-written, but the file sizes are the same. Is this the expected behavior? If not, what's the right way to upgrade them. If this is expected, how can we benchmark the read/write performance with varying sstable sizes. Thanks in advance!
