In Response To: RE: Performance Tuning Discussion (Alexandre Marini)

The metrics script package is ratios.shr_ak. You can download it from the
IIUG Software Repository. The report that it produces displays five basic
metrics which will tell you at a glance how well your server is performing.
The suggested interpretations (described in the report output) assume an
OLTP instance with some DSS style queries present.

Your may also want to look at some of my performance tuning presentations
from past International Informix Users Group conferences which you can
download from the IIUG members' pages once you log in to the IIUG site.
