Jeremy Hanna updated CASSANDRA-14902:
-------------------------------------
Description: compaction_throughput_mb_per_sec has been at 16 since probably
0.6 or 0.7 back when a lot of people had to deploy on spinning disks. It seems
like it would make sense to update the default to something more reasonable -
assuming a reasonably decent SSD and competing IO. One idea that could be
bikeshedded to death could be to just default it to 64 - simply to avoid people
from having to always change that any time they download a new version as well
as avoid problems with new users thinking that the defaults are sane. (was:
