I have a need to export records from microsoft Access and import them into MYSQL. I have purchased applications to do this but the transfer rate is extremely slow, and I don't know why. if I export the table to CSV and load it directly from the server it loads the data really fast. are their any settings I can set on my mysql server to speed up the insert statements. Sorry for the lack of information but I am not sure what I should be including in this

I'm not sure how these statements are being executed.
How are you going from access to mysql?
What I would do is export the access table to a csv - then upload the csv to a temporary table in mysql then insert the values into the correct table.
I'm not sure what control you have.
The reason generally why csv inserts are quite fast is that it loads multiple records at the same time
If you are inserting one at a time then you can get problems with rebuilding indexes (which you can turn off and on with statements)
If you are doing this from access you could also buffer multiple inserting rows into one statement ie
insert into tablename (field1, field2) values (1,2),(3,4)
which is 2 rows in one statement - which will also execute faster.
If your applications are using odbc and not just executing SQL they may be slower too - because the odbc drivers have some known bugs.
