How Visual FoxPro Caches Tables by Using File Caching (136579)
The information in this article applies to:
- Microsoft Visual FoxPro for Windows 3.0
This article was previously published under Q136579 SUMMARY
This article describes the type of file caching that Visual FoxPro performs
on tables.
MORE INFORMATION
Visual FoxPro performs read and write caching on tables opened exclusively.
To flush the write buffers, use the FLUSH command. The write buffers are
also automatically flushed periodically.
Visual FoxPro performs read-only caching on tables opened in shared
mode. The update on the read cache is based on the second parameter
of SET REFRESH.
Visual FoxPro performs its own file caching, so you should limit the amount
of memory given to file-caching software such as SMARTDRV to approximately
256K. This gives more memory to Visual FoxPro, and Visual FoxPro can manage
it more efficiently than SMARTDRV can because Visual FoxPro has more
knowledge of its own disk access patterns.
