To answer these questions, many website-monitoring solutions are available.

Naturally, you have to spend some money to get the best tool. Still, free alternatives offer performance monitoring suitable for small start-up companies. Testing server response time is a big part of the monitoring process. We made a list of the best tools to test website speed and performance.
