Hi All,

We have an application which executes one sql statement more than 10 million times a day. Everything is good about the sql, well tuned, uses indexes, parse only once, etc. The number of concurrent users in this database seems to around 60, but we see an average 1500 executions/sec.

We questioned the developers about the sql as we had seen 80% to 95% latch sleeps on library cache constantly. They seem to be hitting the database every time a page is refreshed instead of storing the retrieved data some where for later use.

The developers are of the opinion that cookies and session variables are considered "the much detested and reviled Satan and Lucifer of all "stateful" web apps".

Any comments/opinion?
