On-Line 7 Performance

We too are having performance problems similar to other postings in this newsgroup. I suppose it is the nature of newsgroups that only problems are posted, but are there any sites that are happy with On-Line DSA. I have implemented recommedation made here and also from Informix support, but nothing has made a significant difference. I would be interested to here from sites that have successfully tune On-Line DSA. For the record, our site is using On-Line 7.2 for SCO OpenServer on a Quad Pentium 60MHz and a Dual Pentium Pro 200 MHz. We have gone back to our old setup of On-Line 5.03 wich out-performs On-Line 7 by about 60%.
