1. You have 8 GB RAM. You have set innodb_buffer_pool_size to 23 GB, It should be about 25% of that.

At the terminal prompt run ...

free -m

and post the results. I think that will show there is a lot of swapping. If that's so, you need better settings and perhaps more RAM.

2. Inefficient queries are clogging your server. They need to be optimised. Turn on the slow query log specifying queries that run more than a few seconds, optimise the queries that it reports.

3. Partitioning cannot solve #1 and #2, and in any case should not be considered until #1 and #2 are resolved.
