Hey,

I recently got started on using docker and have one question: can docker daemon be configured to use multiple CPUs so that I can run multiple docker commands (e.g., _docker run_) concurrently? I found dockerd itself seems only use 1 thread at maximum and when I issue multiple _docker run_ commands at the same time, the requests are queued and the throughput does not scale at all. I searched a bit and didn’t find any option that allows me to increase the number of CPUs / Threads that docker daemon can use. Am I missing something or it is true that docker can only use 1 cpu to run its commands/requests?

Here is my docker info:

Containers: 48  
Images: 6  
Storage Driver: aufs  
Root Dir: /var/lib/docker/aufs  
Backing Filesystem: extfs  
Dirs: 102  
Dirperm1 Supported: false  
Execution Driver: native-0.2  
Kernel Version: 3.13.0-85-generic  
Operating System: Ubuntu 14.04.4 LTS  
CPUs: 2  
Total Memory: 15.67 GiB

Thanks,

- Yong

Changing the file system aufs to overlayfs might help
