Hi, I am doing some evaluation with mango to see the system behavior under a medium/big amount of pointvalues/events.
I notice that until the SQL database is less than 1.5GiB, my CPU consuming goes around 20%. However after 2 or 3 hours running with the configuration above, the SQL DB pass the 2GiB(not sure if this is the source of the problem) and the CPU consuming start growing until keeps in the 90/100% CPU, making mango unresponsive.
CPU: QuadCore Xeon 2.4GHz
Mango 3.5.6 (set to ext-enabled with 6GB)
Created Datasources: 430
Enabled dataSources: 8 virtual datapoints, 100ms update, with 1 random numeric DP each, 1 change event record by update each.
Created Datapoints: 6500
Enabled Datapoints: 10
Writes per second during database batches: 79
Point values to be written: 32 (Average)
Database (reset) size after proceding a backup, deleting the mah2.hs.db and restore it:
SQL Database size 1.8 GiB
NoSQL point value database size: 100.5MiB
Point values Count: 4918301
Events count: 1652711
JVM free memory (MB) 1113 (After a fresh restart)
JVM free memory (MB) 759 (At the lock time)
JVM maximum available memory (MB) 4960
