Monitoring and Troubleshooting Administrators should monitor the log file usage and the frequency of log backups using Dynamic Management Views (DMVs) and Performance Monitor counters. These files ensure that every operation, from a simple update to a complex batch process, is recorded sequentially.
Reducing SQL Server Log Processing Time: Strategies and Best Practices
The log records are written sequentially, which makes the log writes extremely fast and efficient, as the head does not need to jump around the disk. The log records are first sent to the log cache in memory and are flushed to disk based on specific events, such as a transaction commit or when the log block is full.
Without this continuous write-ahead logging mechanism, the integrity of the data would be impossible to guarantee during power failures or system crashes. However, unlike data files, adding more log files does not improve performance in the same way adding data files might.
