Performance-Problems with Online

Hello, my colleague and I have to develop an interface, that substitutes the C-isam-interface which can't be used with Informix-Online. With our Interface we make the same functions (isopen, isstart, ...) available as C-Isam, but this functions work with esql/c or 4GL, so that it is possible to connect to the Online-Server. Everything is working fine, but especially if we make a "read next" (we don't do a "read previous" anyway) about 1.3% of the select-statements we're executing need nearly 1 second to be done. (for the tests we use allways the same select- statement). Is there any possibility to tune the Online- Server, to execute this statements faster or does someone have an idea of what we can do otherwise to solve this problem? Thanks for all your help!
