The cache hit was very low (a topic for another day), and whenever the server had to provide a fresh version of the page, it was taking an unacceptably long time more often than not. Synthetic tests, even properly tuned to match device and network characteristics, only occasionally surfaced the issue.

Sharding: Sharding is the concept of splitting data horizontally, i.e. by distributing data into multiple servers (shards), meaning that the different portions of data for a given table, may be stored on many different servers. This can help to split large data sets into smaller ones stored in multiple servers.

Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). This is one of the main reasons why content delivery networks (CDNs) exist: They place servers physically closer to the end user in order to reduce latency, and thus delay, as much as possible.
