What did you do?

Ran the usual test suite on Mac m1 for my project. Tests usually take around 15s but on m1, take around 2 mins. The source code is available at https://github.com/bigpanther/trober

What did you expect to see?

Expect to see the tests run in under 15s as is the case for non m1 machines.
eg: See https://github.com/bigpanther/trober/runs/1606449367

On further investigation, this does not look like a golang issue. I validated running pure golang tests without third party deps and execution times are as expected. I think the slowness is coming from connectivity to the local docker container.

Tried with another project and the tests times are as expected. Closing this issue as I think it does not need attention in this forum.
