Heroku claims to be measuring “RSS” too, is that different than “private RSS”? sample#memory_total=509.52MB sample#memory_rss=469.41MB sample#memory_cache=40.11MB sample#memory_swap=0.00MB

Still way more than our passenger numbers! Let’s try with passenger…

Passenger on heroku

Having trouble getting passenger working on heroku for some reason…. hmm, without me doing anything it seems to have settled down and is working.

• Just home page query sample#memory_total=376.59MB sample#memory_rss=290.23MB

• Accessing 115-child work ysnh5if, sample#memory_total=415.04MB sample#memory_rss=328.95MB, but then recovers to sample#memory_total=351.00MB sample#memory_rss=264.92MB

• ramelli 4b29b614k, sample#memory_total=459.54MB sample#memory_rss=373.44MB

So not really that different. Maybe a bit better under passenger.

We have a semi-functional app deployed to heroku – no Solr (so no searching), no background jobs, lots of edge case issues. But something to look at.
