How can I render quicker in Sony Vegas?

you'll ideally need to upgrade to a multi core/i3/5/7/9 Intel CPU, Intel is mainly bought/used for video editing and rendering due to its multi core and multi threading capabilities, AMD's a lower end market product and especially having a 2.10Ghz CPu will slow it down considerably, look to invest in something more along the lines of a Quad or an I5-7 with a 3.2Ghz+ rating for quicker speeds.
