I'm running the free instance of amazon RDS connection to a t2.medium ec2 instace. We are running a wordpress website with 20 active plugins and about 800 pages. I can see that I am low in memory (freeable memory) down to 52MB. There is only 1 database connection active and the google analytics real time report show only 1 visitor which is me.
mysql show process list returns
+-----+-------+-------------+-------+---------+------+-------+------------------+ | Id | User | Host | db | Command | Time | State | Info | +-----+-------+-------------+-------+---------+------+-------+------------------+ | ****| ***** | l****:46109 | mysql | Sleep | 4 | | NULL | | ****| **** | ****:33918 | NULL | Query | 0 | init | show processlist | +-----+-------+-------------+-------+---------+------+-------+------------------+ 2 rows in set (0.00 sec)
what is consuming my memory?
SHOW VARIABLES LIKE '%buffer%';
