Maybe but is my impression that *generally* there is a trade off made between space and speed. Therefore a smaller footprint would most likely imply poorer performance. Simon.
Dear anonymous, appreciated the thoughts in your posting. Wouldn't mind getting a direct mail from you. ak

My question is related to the concept of concurrent runtime database licenses. If an organization has a growing database, say they're using something like Informix Dynamic Server, for various things entered by users through their website - also growing (in traffic level). So, the database is updated via the webserver (say, Apache). My question is, how many concurrent user licences do you suspect would be needed for certain levels of traffic. (i.e., X concurrent user licenses for 100 db accesses a day, 1000 db accesses a day, ect). I guess what I'm asking is really a question of probability & statistics (and chaos theory for that matter): 24 hrs in a day, X # db accesses a day (avg) + some math = probability of Y # of concurrent accesses to occur. I would think that those in the db industry would have general benchmarks to go by. From your experience with databases, hope you guys could give me a helpful estimate -- I really have no way hypothesizing... Thanks mucho. -Steve
