-Dcom.ibm.rational.mvfs.checking

Use this property to improve the performance of Multi Version File System (MVFS) file systems.

-Dcom.ibm.rational.mvfs.checking=[true | false]

The WinNTFilesystem methods getModifiedTime and getBooleanAttributes use the windows methods API_wstati64() and _wfindfirsti64() instead of the defaults. This property is not enabled by default because it can cause performance degradation on local file systems. The property also causes degradation on remote Windows shares where there is no Windows directory cache for the remote file system.
