Never done timing tests, but it seems like it could probably look through 1000 items faster than it would take to read from disk. You'd have to experiment and see.>4- What are the PCS recommendations for using this preference?It's tied to the smartcache number of seconds between disk checks (default 2 seconds). Which means every 2 seconds it's hitting the disk anyway. It's designed so that if you're getting 50 hits per second, then 100 hits go thru with no disk hits. If you're sure your content never changes, you could set the smartcache time to 86400 (a day) and never hit the disk once during the day. Our recommendation is to leave it alone unless you have a specific need.But don't be too concerned about disk hits -- even on a 6100/66 it takes about 1/60 second to load a file from disk.Bottom line: experiment. It's not critical enough for us to have a huge discussion about it here on the talk list.Technical Support | ==== eCommerce and Beyond ==== Pacific Coast Software | WebCatalog, WebMerchant, 11770 Bernardo Plaza Court | SiteEdit Pro, PhotoMaster, San Diego, CA 92128 | Typhoon 619/675-1106 Fax: 619/675-0372 | http://www.smithmicro.com/
