> 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.
