Furthermore, the additional cost of more advanced transports can be isolated by comparing their performance with the null transport. .PP The \f(CW\*(C`t/85gofer.t\*(C'\fR script in the \s-1DBI\s0 distribution includes a comparative benchmark. .SH "AUTHOR" .IX Header "AUTHOR" Tim Bunce, <http://www.tim.bunce.name> .SH "LICENCE AND COPYRIGHT" .IX Header "LICENCE AND COPYRIGHT" Copyright (c) 2007, Tim Bunce, Ireland.
