If you're "my documents", Desktop and etc are hosted on a RAID (I've seen these on a 4 drive RAID 5 for 1000 people.) then the speed of that RAID and the fabric to it tend to be massive bottlenecks. I remember my Uni was hosting all the Desktops for every student on a single 8 bay raid that was connected to the network by a single GbE connection. Was not pretty, and 15 minute login times where not fun. -Matt Daubney -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

I guess it is not a selling point i can make. Not thnat it matters... We are moving to w7 and we have just upgaded from office 2003 to 2011. Seems like there is no way out this time. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

Hmmm, that could be down to the age of the machines, the traffic on the network, or maybe if the network drives are hosted on remote servers (we get that where I work, being an international company some of the servers are dotted around Europe or the US and the WAN link is pretty tslow which can cause Windows to hang occasionally or run slow). It could also be using roaming profiles or applying policies which can slow it down. It maybe quicker using Ubuntu, but again it could also be slow too.

I find my work laptop running Windows 7 can run like a dog when it boots up or resumes from hibernation if I have the network connected or wifi on while it tries to find servers. If the network is disconnected and the wifi turned off it tends to not try to find the servers and be a bit more responsive. In my experience with Gnome 2 on Ubuntu I've found that when connecting to a server with a slow connection (such as my home server over a VPN connection) it can in some cases cause Nautilus to hang but the rest of the machine seems pretty responsive.

[ubuntu-uk] Ubuntu in a networked workplace
Curiosity question: If ubuntu was installed in a company with around 1600 desktops and laptops that need to be networked with shared server drives and need to be backed up daily. I guess antivirus and normal security would also be needed. What would be the boot up time of a computer that normally takes 5 to 10 minutes to boot up with XP? The servers run on linux, btw. Would doing a backup still slow the computer down significantly? The reason i ask is that i found that when turning on my work computer (xp) with out of network the boot up speed increased significantly. And was thinking if this problem would be the same even if switching from xp to linux. -- Andrés Muñiz Piniella Sent from my Nokia N900 Please do not send microsoft office documents plain txt or pdf are prefered. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
