Deleting files and directories is slow in a UFS filesystem

Solaris SPARC Operating System - Version 8.0 and later
All Platforms


Running truss on a process thus affected, will show the system call unlink(2) taking tens to hundreds of milliseconds.

This time varies, depending on the size of the file being unlinked.

   $ truss -D rm testfile
0.4962     unlink("testfile")                              = 0

The problem is exacerbated when doing removals of hierarchies of large files.
