improve the performance of any ASP-based Web site. 1.SQL optimization An easy way to improve site performance is to add an index to the date field in the Schedule table, so that it will find between the given dates, thus speeding up the getevents stored procedure. For small sites, we can install SQL on the same server as IIS, and once site traffic starts to grow, we can move SQL to its own server, and w
