amey on "Compaction Tuning"

Hello,
Wanted to know the parameters that can be modified in Cassandra.yaml to increase performance/speed of compaction process.
I have looked at the following :
- in_memory_compaction_limit_in_mb: 256 ( can this be much higher, I read that max can be 10% of heap)
- multithreaded_compaction : true
- compaction_throughput_mb_per_sec: 0 (disable throttling)

Thanks,
Amey
