I added the following configurations to my. cnf file and reran mysqld not to read buffer_pool in subsequent rounds.
Benefits of Buffer Pool Extension.
The buffer pool starts with only the memory required to initialize.
Worker 1 finds information already in buffer pool and does not have to yield for I/O operations.
As long as sufficient memory(between 4 MB and 10 MB) is available to prevent paging, the SQL Server buffer pool will continue to grow.
SQL Server builds a buffer pool in memory to hold pages read from the database.
Minimize physical I/O to the database files by maximizing the size of the buffer pool.
The Arista 7010T switches offer low latency and a shared packet buffer pool that is allocated dynamically to ports that are congested.
The buffer pool does not immediately acquire the amount of memory specified in min server memory.
SQL Server may reduce the commit target of the buffer pool and start trimming internal caches more often.
Much of the code in SQL Server is dedicated to minimizing the number of physical reads and writes between the disk and the buffer pool.
The SQL Server buffer pool is not used; therefore, this memory is available for query processing.
The memory referenced here is query execution grant memory,not buffer pool memory(for example, data and index pages).
The ratio of the Extended Buffer Pool can be between the size of the max server memory and the size of the buffer pool extension of 1:16 or less.
Microsoft recommends a ratio between the size of the physical memory(max_server_memory)and the size of the Buffer Pool extension of 1:16 or less.
When configured with a min server memory setting, the buffer pool does not immediately acquire the amount of memory specified for the min server memory.
The buffer management component consists of two mechanisms: the buffer manager to access and update database pages, andthe buffer cache(also called the buffer pool), to reduce database file I/O.
SQL Server reserves the computed amount of its process virtual address space for the buffer pool, but it acquires(commits) only the required amount of physical memory for the current load.
The only difference is that the buffer pool never drops its memory allocation below the level specified in min server memory, and never acquires more memory than the level specified in max server memory.
Note about SQL Server 2012 Standard Edition(64-bit):Microsoft SQL Server 2012 Standard Edition(64-bit) does not require you to enable any trace flag to allow SQL Server use locked pages for the Buffer pool when the SQL Server service account is granted the Lock Pages in Memory security privilege.
The buffer management component consists of two mechanisms: the buffer manager to access andupdate database pages, and the buffer cache(also called the buffer pool), to reduce database file I/O.
The min server memory and max server memory configuration options establish upper and lower limits to the amount of memory used by the buffer pool and other caches of the SQL Server Database Engine.
Note about SQL Server 2008 R2 Standard Edition(64-bit): Microsoft SQL Server 2008 R2 Standard Edition(64-bit, all versions RTM and later)also requires trace flag 845 to be added as a startup parameter so that SQL Server can use locked pages for the Buffer Pool when the SQL Server service account is granted the Lock Pages in Memory security privilege.
