I am running a mysql server. I would like to somehow make sure that the whole DB is loaded into the ram as I heard it would be alot faster.
Is this true? and how do I vertify it?

If you are using InnoDB, then you can set innodb_buffer_pool_size to be at least as large as your data and indexes. Then as you access data, it will be cached into memory and all subsequent accesses will occur via memory.
If you wanted to pre-cache the data, you could do some of your common queries, or full table/index scans to force it to load all of the data into memory.
There is an init-file option for mysqld which can have the server automatically execute some commands on startup, where you could include the pre-caching queries to execute.
Keep in mind you don’t want to run out of memory, so be careful with setting innodb_buffer_pool_size too large.
