Brad Fitzpatrick	6a2e94cbeb	tstime/rate: deflake TestLongRunningQPS even more ... Previous de-flakings: * 8cf1af8a07 for #3733 * 30458c71c8 for #2727 Fixes #4044 Change-Id: I506cf1ff37bb224f5a9929f1998901e60b24535d Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	8cf1af8a07	tstime/rate: deflake TestLongRunningQPS ... This test set the bar too high. Just a couple of missed timers was enough to fail. Change the test to more of a sanity check. While we're here, run it for just 1s instead of 5s. Prior to this change, on a 13" M1 MPB, with stress -p 512 ./rate.test -test.run=QPS I saw 90%+ failures. After this change, I'm at 30k runs with no failures yet. Fixes #3733 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Joe Tsai	30458c71c8	tstime/rate: deflake TestLongRunningQPS ... This test is highly dependent on the accuracy of OS timers. Reduce the number of failures by decreasing the required accuracy from 0.999 to 0.995. Also, switch from repeated time.Sleep to using a time.Ticker for improved accuracy.

Josh Bleecher Snyder	9da4181606	tstime/rate: new package ... This is a simplified rate limiter geared for exactly our needs: A fast, mono.Time-based rate limiter for use in tstun. It was generated by stripping down the x/time/rate rate limiter to just our needs and switching it to use mono.Time. It removes one time.Now call per packet.
