<blockquote cite="mid:BAY130-W26D981C5E67B998C1804B9F2000@phx.gbl">In the morning the students were on Window boxes using Flash and
Samba. I think some of them were working directly off of the server:
saving/executing. I think that might have slowed things down. I asked
them to copy the file onto their desktops and work from there and then
save it to their folders. It seemed to work a bit better.<br>

<br>>Ah, now that will affect things in a big way. If you've already got a
lot of disk I/O going, that will certainly slow things <br>>down. In your
situation, I'd have a physically separate, dedicated file server with
hardware SATA RAID (level 5 or 10) <br>>and at least six spindles (hard disk
drives); the more spindles here, the better. Any time I do any heavy
disk I/O on my <br>>K12LTSP server here at home, it slows down the server.
Of course, my server has only a SATA RAID 1.<br>
<br>This has been the 2nd class with Flash and the server has been fine. It looks like that might have been the culprit.<br><br><blockquote cite="mid:BAY130-W26D981C5E67B998C1804B9F2000@phx.gbl"> <br>
During the afternoon (they were on a Linux box), there was no noticable
lag. I also asked the students to try to use Opera instead of
Firefox. They complained a bit but it was nice to see the CPU numbers
go down.<br>

<br>> Have them try Konqueror as well. It takes wonderful advantage of
shared libraries (thus lower DRAM usage) and also <br>> will find/use the
Firefox plugins (Flash, etc.). Further, it comes with stock K12LTSP
and thus works with "yum <br>> update".<br>
<br>
<br>I tried Konqueror and I noticed that the cisco.netacad.net site works on it now. I upgraded Firefox and Flash stopped working on it. Cisco Academy said I had to downgrade to get the site to work. The site didn't work in Opera. It only works in Konqueror. Thanks for the tip! I no longer have to go to Windows to view that site. =]<br><br><br><br /><hr /> <a href='' target='_new'></a></body>
