What components or factors can become bottlenecks that reduce the efficiency of the system?

Potential bottlenecks in a system that can reduce its efficiency include:

• Processor (CPU): if the load exceeds the processor's capabilities, the system slows down.
• Memory (RAM): insufficient RAM leads to frequent disk access and reduced performance.
• Disk subsystem (I/O): slow read/write operations slow down application performance.
• Network resources: limited bandwidth or high network latency affect data exchange.
• Databases: slow queries, locks, or poor optimization can become bottlenecks.
• Software: inefficient algorithms, locks, thread synchronization.

Profiling, monitoring, and load testing are used to identify bottlenecks.
