Need Recommendations For Some Connection Properties

Howdy folks,

I'm trying to get a better idea of how I should set some of the SSCE connection properties. I will be deploying the application on a WinCE5 board with a 4G flash storage card and 512MB RAM. The application must run 24/7 with a medium amount of traffic. At any given point I expect up to 3 connections to the same database. I'd really like to keep performance high without risking any database corruption issues. As such, I need to make sure my connection properties are optimized.

I read from Joao's article that setting DBPROP_SSCE_MAXBUFFERSIZE = 1024 gave a considerable performance increase, while anything higher gave diminishing returns. Is this for a certain amount of RAM, or is it uncorrelated to RAM size?

What's the best practice for specifying DBPROP_SSCE_TEMPFILE_DIRECTORY and DBPROP_SSCE_TEMPFILE_MAX_SIZE? Is it possible in WinCE5 to directly put it in RAM? How big do these temp files get?

I've read of some bad experiences with autoshrink. Are there any reasons not to set DBPROP_SSCE_AUTO_SHRINK_THRESHOLD to 100 if the database will be compacted regularly?

Any other advice for the more obscure settings such as DBPROP_SSCE_FLUSH_INTERVAL or all the lock settings?

Thanks a bunch!
