I have the same problem. Insert into's are painfully slow. I do not have spatial indexes and have removed all indexes from tables. I am using INNODB and frequently get the dreaded too many locks error. If I import as a CSV using the mysqlimport the files take under 2 minutes. When I then insert from my staging tables to live it takes over 2 hours.
I can do the same insert into's in SQL Server in 4 minutes. But I am stuck with MySQL for this project.
