Performance Tuning SQL Server Transactional Replication

In transactional replication, the transaction log of the database involved in replication is both written to and read from. Without replication, a transaction log is almost always written to, and rarely read from. Because a transaction log is both written to and read from when using transactional replication, this can cause I/O performance issues on […]

Performance Tuning SQL Server Snapshot Replication

When snapshots are performed, try to schedule them during less busy times of the day. A snapshot not only has to perform a SELECT on the entire table being replicated, but it also has to move the selected data off the publishing server onto the distribution server, which can produce a lot of I/O overhead. […]

Performance Tuning SQL Server Merge Replication

In merge replication, the publisher, distributor, and the subscriber all play a part. Because of this, it is important that each of these hardware systems be properly tuned for best overall merge replication performance. Pay particular attention to the I/O performance of the publisher and subscriber (the distributor only plays a very small part in […]

SQL Server Replication

If your current SQL Server is overwhelmed with work and performance is suffering, one option is to move part of its workload onto one or more additional SQL Servers using replication. Replication allows you to “scale out” your SQL Server by distributing the processing load over multiple servers. For example, you might want to consider […]
