Jonathan Ellis commented on CASSANDRA-8888:
-------------------------------------------

It seems like a lot people have high anxiety about cross-dc bandwidth, justified or not.  What about setting it to cross-dc compression only by default?

> Internode compression increases GC load, and can cause high CPU utilization for high throughput use cases. Very rarely are customers restricted by intra-DC or cross-DC network bandwidth. I'de rather we optimize for the 75% of cases where internode compression isn't needed and then selectively enable it for customers where it would provide a benefit. Currently I'm advising all field consultants disable compression by default.
