I upgraded my mysql on my laptop to the MariaDB which is using the jemmalloc as you stated and that seems to work well.
However on the servers it is running the Percona mysql 5.7.14 and there are no specific malloc libraries configured. >From what I understood , this then uses the normal OS malloc libraries , but this has proven to be problematic. So even if I can setup jemmalloc as a test to see if it makes a difference, that would help, however I am not sure how to enable / install it on percona mysql 5.7.14 though so this is where I need some help. I would really appreciate any help here.
