Which daemon is known to be faster than 'syslogd' for processing system logs?

The daemon that is recognized for being faster than 'syslogd' in terms of processing system logs is 'rsyslogd.' This is because 'rsyslogd' offers several enhancements over the traditional 'syslogd,' including improved performance, support for a wider range of features, and the ability to handle high volumes of log data more efficiently.

'Rsyslogd' implements a multi-threaded architecture, which allows it to process multiple log messages simultaneously, thereby increasing throughput and reducing the time it takes to write logs to disk or send them over the network. Additionally, it supports various protocols for log transmission and can handle various input formats, making it more versatile for modern logging needs.

In contrast, 'syslogd' is the older, traditional logging daemon that does not incorporate these modern enhancements, resulting in slower performance, especially in environments where high log volume is common. The other options listed, such as 'journalctl' and 'logrotate,' serve different purposes; 'journalctl' is a command-line tool to query and display logs collected by the systemd logging system, and 'logrotate' is responsible for managing log file sizes and rotation, rather than directly processing log data.
