Benjamin Mahler updated MESOS-1757:
-----------------------------------
Labels: twitter (was: )
Description:
The full test suite is exceeding the 8 minute mark (470 seconds on my machine),
this epic is to track techniques to improve this:
# Now that the master and the slave have to perform sync'ed disk writes,
consider using tmpfs (e.g. under /dev/shm) to speed up the disk writes. For the
master, we could also consider defaulting to in-memory state rather than the
replicated log for most tests.
# -The reaper takes a full second to reap an exited process (MESOS-1199), this
adds a second to each slave recovery test, and possibly more for things that
rely on Subprocess.-
# The command executor sleeps for a second when shutting down (MESOS-442), this
adds a second to every test that uses the command executor.
Additional options that hopefully will not be necessary:
# Use automake's [parallel test
harness|http://www.gnu.org/software/automake/manual/html_node/Parallel-Test-Harness.html]
to compile tests separately and run tests in parallel.

Updated now that MESOS-1199 is resolved.
