Docker is very slow - 'vmmem' is consuming all CPU


#1

I have a dev setup running under windows with linux-based images for 1) my app server and 2) a postgres server.

While running docker recently after updating my Windows to the October update (1809), I am seeing that the response times for even simple queries have become abysmally slow (10 seconds instead of somewhere around 50ms).

I suspect it’s this Vmmem process which is causing the issue - it’s consuming as much as 60% CPU while consuming nothing else, and I noticed that the CPU usage only flares up whenever I start seeing the response times rising, so there might be a correlation.

This has made running docker under Windows a very painful experience. I tried searching for related issues, but didn’t find any relevant ones. Is there any fix for this which I can do to solve it?
