CompTIA Linux+ XK0-005 Practice Question
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?
Decrease the amount of RAM in the system to reduce the memory available for disk caching.
Increase the CPU clock speed to process I/O operations faster.
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.
