Does transaction log size affect performance?
If the transaction log file is full in the SQL Server database, it degrades the performance of the SQL Server. It also slows down the speed of the transactional log backup process. In addition, the over-sized transaction logs decrease the disk space also because old transaction logs are not removed yet.
What is transaction log What are the typical kind of records in a transaction log?
A transaction log basically records all database modifications. When a user issues an INSERT, for example, it is logged in the transaction log. This enables the database to roll back or restore the transaction if a failure were to occur and prevents data corruption.
What is transaction log how it is useful in transaction processing?
Every SQL Server database has a transaction log that records all transactions and the database modifications made by each transaction. The transaction log is a critical component of the database. If there is a system failure, you will need that log to bring your database back to a consistent state.

Why is transaction log so big?
Therefore the most common reason I have experienced for a transaction log file to have grown extremely large is because the database is in the FULL recovery model and LOG backups haven’t been taken for a long time. * Its important to note that the space within the transaction log is just marked as available again.
