Correct me if I'm wrong, but I think you mis-read that.

The columns are total, used, free.

So at that moment, there was 316MB swapping. (I totally agree and understand that any swapping reduces performance.)

Also at that moment, there was only 426MB free physical RAM,
so increasing the innodb_buffer_pool_size by an additional 30GB would be bad, I think?
