System performance problems refer to issues that hinder a computer or network from operating efficiently. These problems can manifest as slow response times, frequent crashes, or unresponsive applications. Common causes include insufficient hardware resources, such as low RAM or an outdated CPU, as well as software issues like bugs or poorly optimized code. Another factor contributing to system performance problems is network congestion, which can slow down data transfer rates. Additionally, excessive background processes or malware can consume valuable resources, further degrading performance. Regular maintenance, such as updating software and monitoring system resources, can help mitigate these issues.
