So, based on what you are saying, I should be better off putting an extra 02 Gigs ram on the server (04 gigs total for 06 or 07 clients) than running Local Apps on the 486s, right?<br><br><div class="gmail_quote">On Wed, Aug 8, 2012 at 1:43 PM, Jim Kinney <span dir="ltr"><<a href="mailto:jim.kinney@gmail.com" target="_blank">jim.kinney@gmail.com</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Yes. Local apps use the hardware of the actual client. If the client<br>
is setup to find and use local drive for cache, then that makes things<br>
better than using server-side ram caching. Older LTSP used only<br>
server-side. After LTSP5 client-side was an option. It had to be<br>
turned on for each client I think. It's been a few years since I've<br>
done a LTSP install so I'm rather rusty.<br>
<br>
Local apps can require stronger hardware than all server-side only. An<br>
i486 is pushing limits for local apps. Local apps are good for things<br>
that are graphics intensive (flash, video like you-tube, some games -<br>
tuxmath). The issue is that ALL of the libs needed to run the app must<br>
ALSO be local so RAM becomes an issue for older systems as thin<br>
clients.<br>

Every time you stop a school, you will have to build a jail. What you<br>
gain at one end you lose at the other. It's like feeding a dog on his<br>
own tail. It won't fatten the dog.<br>
