If it is then it is pointing to a kernel performance issue.  Because
there is very little difference between them.  Until recently rm used
unlink(2) and there would have been no difference.  But recent
versions of coreutils now use unlinkat(2) for improved security now
instead.  Any difference in performace would be in the realm of the
kernel internals.  It doesn't seem to me like there should be any
significant difference.
