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!). Expect closer to 75ms.

As indicated, SQL Server 2016 added the use of SSE and AVX instructions in various code paths to improve performance. This post will outline SQL Server’s decisions around SSE/AVX or software algorithm use. SQL Server asks the CPU if it supports SSE or AVX in order to determine the level of hardware support present on the system.
