have you tried running all the onstat options to see what is
happening? Long spins? checkpoints?
onstat -g act - which threads are active.
onstat -g rea - which threads are ready to run.
onstat -g sch - long spins
onstat -D - any disk I/O
onstat -B - page cleaning
onstat -F - page writes
go into onmonitor as informix and run Status->Profile and hold down
the return key - which values change?
E-mail me if you want more info.
