Looking at http://www.sqlalchemy.org/trac/attachment/wiki/ProfilingResults/sqla.insert.prof.png this is in the ballpark of whats expected. You can about double your performance by compiling the insert and using the result instead of the insert clause. And if that is not enough you can buffer insertable data into a list and execute many rows at a time, this should dramatically decrease SQLAlchemy overhead.
