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. The first—and often most surprising for people to learn—thing that I want to draw your attention to is that TTFB counts one whole round trip of latency. But what else is TTFB?

Every unnecessary bit of JavaScript code you bundle and serve will be more code the client has to load and process. The resource loading waterfall is a cascade of files downloaded from the network server to the client to load your website from start to finish. How will you serve blazingly fast code, then?

Time To First Byte (TTFB) This is the time it takes for the first piece of information from the server to reach the user’s browser. You need to beware that slow server response times can significantly increase TTFB, often due to server overload, network issues, or un-optimized logic on the server side.

Many database administrators find themselves having to support instances of SQL Server Reporting Services (SSRS), or at least the backend databases that are required for SSRS. These topics apply to both SQL Server Reporting Services as well as Power BI Report Server. Installation and support of SSRS can be confusing.
