Hello, we’ve been running the aggregator with PHP7 in production now for a good 4 weeks. The aggregator seems to work great.
We have noticed a decrease of the server CPU cycles by 50% when upgrading to PHP7. Also non-cached requests are handled twice as fast now (avg. 2s -> 1s) according to New Relic. So it seems your refactor of the plugin was totally worth it because of the overall speed improvements site-wide. Thanks!
