A system administrator notices that a Linux server is experiencing slow performance, specifically in disk operations. Upon investigating, the administrator discovered that the I/O wait time is considerably high. Which of the following actions is the BEST course of action to reduce the high latency affecting the system?
Replace the current I/O scheduler with one that is better optimized for the system's workload.
Deploy additional network interfaces to balance the I/O load.
Increase the CPU clock speed to process I/O operations faster.
Decrease the amount of RAM in the system to reduce the memory available for disk caching.
