The application is a canned package from an international vendor. Their product supports MSSQL and MySQL, and for the past 8 years or so their recommended engine has been InnoDB. We do not have access to the code.

The constraints are what they are. I don't have enough RAM and cannot increase it, so queries are going to hit the disk. The question then becomes, can anything else be done to ease the performance pain somewhat?
