Informix 7.1 performance on AIX 3.2.5 machine.

Hi, We have been running our application which is compiled under Informix 5.2 and the performance seemed to be pretty good. When we moved our upgraded Informix rto 7.1 engine the performance is really bad. We have processes that use to take few minutes under Informix 5.0 are taking hours to complete. We have not compiled our application under 7.1. System Configuaration : IBM RS6000, AIX 3.2.5, 128 MB RAM and 700MB of database space. I really need help on this problem, if anybody has done performance tunning under 7.1 please give me a call or send me an e-mail. I tried to get Informix Tech support but they don't seem to have any clue except asking me add one more processor to the system. I really appreciate your help on this proble. Thanks in advance, Shyam --- -- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Shyam Davuluru Phone #'s: (408)249 3062 (R) Email Address: shyam@minerva.robadome.com (408)492 7328 (W) Siemens Rolm Communications
