Yep, seeing a much more severe hit on all our elasticache instances than anywhere else. CPU graph from two underused ones: https://twitter.com/Adys/status/94943

- necubi 9y agoWe also saw a huge hit on our memcached elasticache nodes. Eyeballing from our CPU graph, seems ~30%.
- berbec 9y agoI've noticed a big slowdown in PV EC2. One machine used to be fine running apache and mysql. I had to add a 2nd cpu and split the mysql off onto a different instance to keep load to manageable levels.
- static_noise 9y agoThe two graphs have different y-axis-scales.
- scrollaway 9y agoObviously? They're two different instances.
- Washuu 9y agoHydra/Gamepedia got hit by the patch on its Elasticache instances around the same time. Redis is used heavily on its caching infrastructure and the web nodes starting thrashing due to the sudden performance loss.(Until the resources were increased.)
