sqlite usually will work great as the database engine for low to medium traffic websites (which is to say,99.9% of all websites). The amount of web traffic that sqlite can handle depends,of course,on how heavily the website uses its database. Generally speaking,any site that gets fewer than 100K hits/day should work fine with sqlite. The 100K hits/day figure is a conservative estimate,not a hard upper bound. sqlite has been demonstrated to work with 10 times that amount of traffic.
