In several previous retrospectives the issue of long wait times for Gerrit reviews has come up. In order to quantify the problem I have written a little script which looks at patch sets submitted to Gerrit in the last year and measures how long each patch set waited for a review.
https://git.beaker-project.org/cgit/beaker-administrivia/commit/?id=0ce9db18...
The "time to first review" is defined as the period of time between the patch set's creation in Gerrit and the first comment written on it by someone other than the patch author or Jenkins.
For now, you can see the output of the script running each night here:

We can find a more permanent home for the graph in future if it turns out to be useful.
