Hey guys,
Got a bit of an unusual problem with my new FC6 installation. If I logon as a normal user the system responds really slowly (eg If I try to open a program, the "starting program" box will appear on the taskbar panel for 30+ seconds until the program loads). Although If i then login as root and then try and start a program, it will load relatively quickly.

Does anyone know what might be causing this problem, or had any similar problem?

Any help is much appreciated, its really starting to piss me off.

Cheers,
Kieran

Try this. Open 2 terminals, side by side.
In the first one, run 'top'.
In the second one, run the application that is loading slow.

Examine what the 'top' terminal shows you. It will tell you what is running and what is using up all your cpu, etc.

Have you already solved the problem? If so, then could you please post the answer here.

My notes on this issue (assuming it is the same issue):

• When I stop network service, everything goes smoothly.

• When network is started, root has all ok, but normal users will have a s-t-i-c-k-y gnome environment. Example:
  # gedit -> ~1 sec
  $ gedit -> ~10 sec

• I have only WLAN to connect to internet, so I can't say if the same problem remains when connected through wired interface.

• I also use ndiswrapper 1.28 with Broadcom driver 3.140.16.0 for the WLAN. I also tried to configure bcm43xx-fwcutter, but I couldn't get it working.

• When starting applications, CPU stays at 0 %, so it seems to be some kind of a locking issue of some global resource.

• If networking is started automatically at the boot, the following services takes much longer to start, compared to when booting without networking:
  system logger
  NFS statd
  cups
  sendmail

• My system: Acer Aspire 3003LMi; Broadcom BCM4318 802.11b/g WLAN adapter, 1.8 GHz AMD Sempron, 512 MB DDR.

I don't know if this is an issue of networking in general, WLAN in general, ndiswrapper or gnome.

Hi Nisu,

Your problem could be because of your /etc/hosts settings. Make sure you have seperate lines for your loopback address and another line for the eth0 address. Also make sure hostname is set in /etc/sysconfig/network file. Hope this helps.

Adding my local hostname to /etc/hosts solved the problem:
--zip--
127.0.0.1 localhost.localdomain localhost
127.0.0.1 Aspire <--- This line fixed it!
--zip--

Now the (gnome) applications pops up fast for all users. I think that even the response times for root are now improved.

Do you know why the response times are so different between the root and the users, when there is no local hostname in the hosts file? And why on earth the system doesn't know that its hostname should be mapped to 127.0.0.1?

Yours,
Mikko

Hi,

I also had the same problem. It began soon after I disabled support for IPv6. My hosts file still contained the IPv6 address for localhost.localdomain localhost instead of the IPv4 version. It had not occurred to me that the hosts file would be the blame for this issue, particularly since I never had this problem in FC2, FC3, FC4 or FC5. As soon as I corrected my /etc/hosts file, as nisu explained above, my problem was solved!

Thanks!
