But I have personally done a benchmark on a large OLTP system on HP and saw a 10% reduction in average transaction time due to changing only KAIO. I heard from an Informix tech who personally did his own BM and found the performance breakpoint was at about 3,000 concurrent (simulated with Tuxedo(?)) users, after which KAIO significantly hurt performance. Up until that point it helped, but I don't recall exactly how much. Aside from that, and the caveats mentioned in the release notes for certain versions on HP, I don't know of any reason *not* to use KAIO of your platform supports it.
