Since I wasn't seeing much of a performance boost with FastCopy, I then tested with uncompressed files.

FastCopy was only about 7% faster.īoth of the above tests were done on compressed files. Using the normal Windows copy method, the 11.7 GB file copied across the WAN in 55 minutes. I then tried copying an 11.7 GB file in a different environment, one where file copies seem to take forever over the WAN. FastCopy was about 16% faster than the Windows copy method. Using FastCopy, it copied in 1 hour and 53 minutes.

Using the Windows copy method, the 35.8 GB file was successfully copied across the WAN in 2 hours and 15 minutes. I had heard about FastCopy, which claims to be the fastest Windows copy product, so I decided to do comparison tests. The database is about 110 GB in size, but since we use Quest's LiteSpeed product, the full backup is just 35.8 GB in size. Recently I had to setup database mirroring for a largish database, so I needed to copy the full backup to the mirror server.

If you've ever had to copy large files on a Windows platform using the Windows copy method (copy/paste in Windows Explorer or copy/xcopy commands), then you know how slow it is.
