while running a sample of statsd traffic in https://phabricator.wikimedia.org/T101141#2194657 it looks like mediawiki accounts for a good chunk of the stats, specifically MediaWiki.db.commit_masters and MediaWiki.image_cache.hit look like very heavy hitters, image_cache is counter and just "1" gets sent ~1.5M times a minute, can we batch it and/or send it less frequently?
ditto for db.commit_masters (commit-masters in MW's code) though that is a timer
