Hey everyone,
I’m setting up a new Windows server for SQL Server and I’m not sure about the virtual memory settings. Can anyone share some tips on how to choose the right pagefile size?
I’ve heard different opinions on this. Some say to make it as big as the physical RAM, others suggest a fixed size based on the server’s role. What’s your take on this?
Also, does it make a big difference for SQL Server performance? I’d really appreciate any advice or best practices you can share. Thanks!
In my experience, the ideal virtual memory size for SQL Server on Windows depends on several factors. Generally, I’ve found it best to let Windows manage the pagefile size automatically. This approach has worked well for most of my SQL Server installations.
However, if manual control is preferred, a good rule of thumb is to set the initial size to 1.5 times the physical RAM and the maximum to 3 times. This strategy provides sufficient growth capacity without overly consuming disk space.
Keep in mind that SQL Server is designed to efficiently manage its own memory; heavy reliance on the pagefile can indicate underlying configuration issues or insufficient physical RAM.
hey, just wondering if your sql server’s memory use has been tracked closely? sometimes even smaller pagefiles could work if you have low oltp workload. what kind of queries are running? would love to know more about your system setup, this might help refine the recommendation.
yo ryan, virtual memory size isnt super critical for SQL Server tbh. it mostly manages its own memory. i usually go with 1.5x physical RAM for initial size, max at 2x. but rly, letting Windows handle it works fine too. whats ur server specs? that could affect things
