Defragment all local hard drives. While the Windows operating system includes a defragmentation tool, it does not not always work properly, so Esri recommends using a third-party defragmentation software. Many applications are available for purchase.
Eliminate as many background programs that are running as possible. Run an anti-spyware application to eliminate any spyware software as spyware degrades the computer's performance.
Increase the amount of RAM in the computer to recommended minimum amount or higher, upgrade the video card in the computer, and make sure there is at least 10 GB of remaining free space on the local hard drive. See the link in the Related Information section for Esri System Requirements.
