Checking Memory Usage

Use

Before you change the size of a buffer, you should determine how much memory the buffer is currently allocated. This is important because the memory that is allocated to buffers should not significantly exceed the size of the physical memory, otherwise operating system swapping will occur.

Most server memory resources are used by the:

Operating system (usually around 30 MB)

Database system (See the database documentation)

SAP System

Procedure

To check the memory usage, from the initial screen, choose Administration → System administration → Monitor → Performance → Setup/Buffers → Buffers → Goto → Current local data → Additional functions → Storage.

You should allocate as much memory as possible to ensure that good buffer quality.

It is usually more effective to allocate memory to the SAP buffers than to the database buffers. However, once the buffers are optimized (that is, no more object swaps occur), it does not make sense to increase buffer size further, since this will not improve performance.
