For example: - the CPU can't keep up with the number of requests; - a slow disk drags down reads and writes; - insufficient RAM triggers frequent disk access; - inefficient queries or indexes slow down data processing. Because of that bottleneck, the whole system runs slower, even if every other component could otherwise run faster.For the reviewerNote to the moderator (optional)Visible only to the moderator.
