What is performance tuning explain with requirements for it?

Performance tuning is the improvement of system performance. Modify that part of the system to remove the bottleneck. Measure the performance of the system after modification. If the modification makes the performance better, adopt it. If the modification makes the performance worse, put it back the way it was.

Why performance tuning is required?

Performance tuning lets you build indexes and eliminate problems which could cause your data retrieval to be slower than it has to be. Nothing frustrates your team of employees more than waiting for the database to conduct its searches. That will lead to more frustration reaching your customers or clients.

How can SAP performance be improved?

1. Consider database buffers are not sufficient [increase buffers]
2. Consider resources bottle on the database [check memory and CPU utilization]
3. DB indexing issues [check missing indexes in DB02]
4. DB statistics are outdated [schedule DB stats job in DB13]
5. Db has to be re-organized [Reorganize the DB using Brtools]

Are there hard and fast rules for tuning server performance?

Because no two server environments are identical, we can’t provide hard and fast rules for tuning server performance. However, you can draw conclusions about performance from patterns in the data that you collected. For example, are there recurring spikes?

What are the buckets for database performance tuning?

When it comes to database performance tuning, separating potential issues into buckets means organizing everything based on commonality. For databases and tuning SQL, the buckets can be thought of as: Concurrency (blocking – multiple threads requesting locks on the same database resource)
