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 DBI distribution includes a comparative benchmark. .SH AUTHOR .IX Header "AUTHOR" Tim Bunce, .SH "LICENCE AND COPYRIGHT" .IX Header "LICENCE AND COPYRIGHT" Copyright (c) 2007, Tim Bunce, Ireland.
