A lot of people surmise that TTFB is merely time spent on the server, but that is only a small fraction of the true extent of things. TTFB isn’t just time spent on the server, it is also the time spent getting from our device to the sever and back again (carrying, that’s right, the first byte of data!). But what else is TTFB?

Simple parameterization has a number of quirks in this area, which can result in more parameterized plans being cached than expected, or finding different results compared with the unparameterized version. When SQL Server applies simple parameterization to an ad-hoc statement, it makes a guess about the data type of the replacement parameter.

Its raison d’être is to cache result rows from a plan subtree, then replay those rows on subsequent iterations if any correlated loop parameters are unchanged.
