           Summary: KDE 4.7 is very slow on ext3 root partition
           Product: kde
           Version: 4.7
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: nicolamori at aol.com


Version:           4.7 (using KDE 4.7.1) 
OS:                Linux

After upgrading to 4.7.0 I noticed a slowdown in my i686 installation. In
particular, KDE start is very slow and opening lancelot for the first time
after boot makes the system unresponsive for 5-10 seconds. I find similar
"short freezes" also with sutdown dialog and some application launch. During
these freezes the HDD spins a lot so I suspected some I/O problem, and I
finally tracked it down to having an ext3 root partition. I did two fresh
installs of Archlinux, one using ext3 as root fs and the other one using ext4:
the first is problematic while the latter works perfectly.

Reproducible: Always

Steps to Reproduce:
Do a fresh install of Linux (I tried with Archlinux) using an ext3 root
partition, then install KDE and lancelot. Launch KDE and click on lancelot
launcher.

Actual Results:  
Startup is slow, lancelot menu pops up very slowly at first launch then it pops
up quickly at successive clicks.

Expected Results:  
Startup should be quick and lancelot should pop up quickly also the first time.
