[xwiki-users] file operations in file system storage is too slow

HI! Xwiki 3.1. Attachment versioning turned off. Storage is set to file system, Works fine with relatively small files. I uploaded 700M file - no problem, a bit to wait, but works fine. I tried then to delete this file. The result was also successful, but took nearly 1.5 minutes to finish. Is there any way to run file operations faster? Thanks a lot. Dmitry Bakbardin.
