In my dev machine,rethinkdb is consuming almost 5gb memory.it is big waste,so I add this line "cache-size=512" to "/etc/rethinkdb/instances.d/default.conf",then restart it,but it still consumes almost 5 gb memory,why?
by the way,I have 70 tables,and all empty(some may contains 1~5 records for testing),and configuration is:
ubuntu 14.04 64bit 8gb memory
rethinkdb 1.15.2 64bit
