rtt_thresholds

Hot Reloadable

Applies only when the s2_auto mode is used and defines the round-trip time (RTT) thresholds for compression level changes.

By default, no compression is used unless the RTT hits the first threshold (e.g. 10ms), then s2_fast. The next threshold would switch to s2_better, and then finally s2_best is the last threshold is reached.

Note, the compression level is dynamic so if the RTT decreases, the compression level will decrease accordingly.
