These are a bit more conservative, but will hopefully come with improved stability like https://skia-review.googlesource.com/c/skia/+/111740 did. If this works, we can push the envelope by using the slightly more aggressive settings found at https://android.googlesource.com/platform/platform_testing/+/master/scripts/perf-setup/dragon-setup.sh Bug: skia:7238 Change-Id: Ia0e24c7fc9bcc2fd44dcd0a57dde481ad8c55f7d Reviewed-on: https://skia-review.googlesource.com/114283 Reviewed-by: Kevin Lubick <kjlubick@google.com> Commit-Queue: Kevin Lubick <kjlubick@google.com>
