Description
I've been trying to identify the root cause of a major slow down in tests when running in 3.2, but have found nothing obvious so far, except for some pretty high disk activity during tests.
To reproduce, start the test suite databases (there are several of them, in varied setups to exercise several different aspects of the driver):
make startdb
|
and then run a selection of tests; GridFS is a good example as they are all passing with 3.2 and most of them are very simple:
go test -check.v -check.f GridFS
|
In Gabriel Russell's machine, this was the result as of yesterday evening:
[gabriel@earthshaker mgo.v2]$ go test -check.f GridFS -check.v
