Warmup Cache Request can have fewer advantages when it is not planned correctly. Warmup Cache Request occasionally is not configured correctly in the middle of trouble shoot threads to either warm too many URLs simultaneously or at any given time of the day when the traffic is the heaviest. This may result into wastage of server load and reduce response time. Warming outdated URLs that do not get traffic anymore is another issue that is also common. The consistency of audits and selective targeting ensures efficiency. What were your lessons after the first implementation of warmup?
