I have a MySQL database which dumps to a 3.5 GB backup (mysqldump) in about 10 minutes.

But reloading this backup on a standby / test server takes upwards of 12 hours.

What are some settings that would maximize reloading performance?

The most promising appear to be innodb_buffer_pool_size, innodb_additional_mem_pool_size, and innodb_log_buffer_size... but I'm reaching the limits of my trial-and-error approach. Which of these settings "should" be the most important?

Through trial-and-error I was not able to get more than 70% CPU utilization and 63% memory utilization. I'd like both at 100% during a reload.

All tables are InnoDB.
