A content delivery network (CDN) is a distributed network of servers strategically located across multiple geographical locations to deliver web content to end users more efficiently. When an edge server goes down, end users in the affected region may experience an increase in latency for that specific location.

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!). But what else is TTFB?

Questions Q: I have a MySQL server with 500 GB of RAM; my data set is 100 GB. ChatGPT: The InnoDB buffer pool is used by MySQL to cache frequently accessed data in memory. Keep in mind that setting the buffer pool size too high may result in other processes on your server competing for memory, which can impact performance.

When SQL Server reads data under locking read committed isolation (the default for non-cloud offerings) and chooses row-level locking granularity, it normally only locks one row at a time. SQL Server solves this problem using lock classes. Lock classes are needed for key lookups when a blocking operator is present before the lookup.

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.
