--------------------------------------
Summary: hs2-http 3x slower than hs2 with high-latency network
Key: IMPALA-10354
URL: https://issues.apache.org/jira/browse/IMPALA-10354
Project: IMPALA
Issue Type: Bug
Reporter: Kurt Deschler
Attachments: hs2.svg, http.svg
Performance testing of simple create/drop function with simulated high network latency shows a 3x performance difference between the hs2 and hs2-http protocols.
Simulated latency:
sudo tc qdisc add dev lo root handle 1: prio priomap 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
sudo tc qdisc add dev lo parent 1:2 handle 20: netem delay 1000ms
sudo tc filter add dev lo parent 1:0 protocol ip u32 match ip dport 28000 0xffff flowid 1:2
sudo tc filter add dev lo parent 1:0 protocol ip u32 match ip dport 21050 0xffff flowid 1:2
