I doubt anyone could really say.  It is possible but
unlikely.  The biggest factor affecting performance on local
transfers is the disk subsystem bandwidths and disk layout.
That is of course predicated on the assumption that you are
using --whole-file which was apparently not the default for
local transfers in 2.3.1

Given the number of bugfixes and the impossiblilty of
supporting such an old version an upgrade is recommended.
