Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.

When this data block is read, it decompresses it in memory and presents it to the incoming request. When data is written to disk, MongoDB compresses it with a specified block compression method and then writes it to disk. Block compression can improve performance by allowing data to be read and written in smaller chunks.

Websites are now more than just the storage and retrieval of information to present content to users. Web monitoring is a comprehensive term that describes the activity of testing a website or web application for its availability and performance. HTTP monitoring allows you to test availability and performance from around the world.
