<p class="MsoNormal"><span style="font-size:10pt;color:black">does anyone know if there is a router memory calculator like there
is a DSP calculator?<br>
<br>
i'm trying to decide to stick with the default 1GB of memory on the 3945s or
buy the 1GB upgrade for a very good price.<br>
<br>
if i stick with 1GB and have to upgrade later, the cost is more, but at least
i'm not throwing away money (it's replace, not add).<br>
<br>
what are the chances of me needing more than 2GB on a router? what is taxing on
memory in a router config?<br>
<br>
i will be loading the router with:</span></p>
