The disadvantage to using more threads is that when the threads are used, more memory is used on the NFS server. Any use of the network runs a higher risk of data loss than local disks. Rather than using NFS for this task, use explicit data duplication, via one of the long-established mechanisms designed for this purpose. this content This can cause problems as administrators and automatic cleanup software may delete files that have remained unused for a long time, expecting them to be stale lock files, abandoned temporary files
