Why is the server so slow? CPU, RAM, and disk I/O resources are exhausted, and ram is used up
Machine running is slow because it consumes too many system-specific resources. The main resources of the system include CPU, RAM, disk I/O, and network. Excessive use of any of the

In this case, I usually run multiple uptime commands consecutively (or use the top command) to see if the load is going up or down2. What is the high average lo
