Docker 1.9 serious performance issues #17720
Description
A couple huge dealbreaking issues on 1.9 for me right now:
Docker ps on relatively modest number of containers is taking forever
coderpad@execute6:~$ time docker ps | wc -l
26
real 0m42.655s
user 0m0.016s
sys 0m0.004s
Container startup latency times have gone through the roof.
coderpad@execute6:~$ time docker run hub.coderpad.io/coderpad:base echo hello
hello
real 0m2.173s
user 0m0.020s
sys 0m0.000s
coderpad@execute6:~$ time docker run hub.coderpad.io/coderpad:base echo hello
hello
real 0m3.491s
user 0m0.020s
sys 0m0.000s

These boxes were running 1.8 in an identical configuration prior and doing fine
