the tools you mentioned are great.
however, Adager and dbgeneral require exclusive access to the database
and except for mapping of one record to another format do not change the
data in the database.  datanow only uses standard image intrinsics for
updating the data in the database.

perhaps you should look at other ways to improve performance.  perhaps
additional memory or splash compiler to convert code to run in native
mode would better serve your purposes.
