The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

Been a while since I looked at the system limits documentation, but I'd
think you'd need a decent sized i to handle 50K active jobs ...
I think we're getting to the heart of the matter. Open connections (active jobs) use system resources. On the other hand, rerunning SQL statements and saving and restoring state with each request uses system resources too. The former is memory intensive while the latter is CPU intensive. So which constraint is going to be more problematic?
Say it takes an extra 25 milliseconds of CPU time to rerun an SQL statement and save and restore state. Say 50,000 users are making requests at 10 second intervals. That would mean 5,000 requests per second. You'd probably need about 15 additional cpu's just for the extra workload.
I see trade-off's either way.
Nathan.
