So this is kind of interesting. My rather small eventstore test is now using 26+ GB of virtual memory (actually at one point it said 0.113t in TOP - which I have never seen before…)
Running a fresh install of Ubuntu 16.04.2 LTS xenial
EventStore version 126.96.36.199 (HEAD/f1880e43483394efb96759eab903de2f1a679f58, Wed, 30 Nov 2016 11:54:21 +0000)
This is running on a Gen2 VM under Hyper-V with 512MB initial ram and dynamic ram availability.
loaded up ~6000 events, each containing about 10KB json data
have a total sum of 2 projections in the DB, first one splits and emits the above events to ~426 streams
The second one reads out a lot of smaller chunks of data from the above events from and emits into around 4000 streams
I have also been doing a number of queries while working out some more projections - but nothing fancy.
Disk space in use, 707 MB:
