Summary: Application are very slow on encrypted partitions
           Product: Wine
           Version: 0.9.59.
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Hi,

Yesterday I encrypted my /home partition using cryptsetup and luks format.
My system (Kubuntu 7.10 up to date) is running well but all Windows application
are very slow.

I tried to unmount my encrypted /home and mount the unencrypted one (my backup)
and the problem disappeared.

Have you looked into why this is happening? Is there heavy CPU usage or lots of
disk I/O? Is everything slow? Even notepad and winecfg?

I think it is a problem of read/write on the encrypted partition. But I do not
understand why only applications executed with Wine are concerned.
> Is there heavy CPU usage or lots of disk I/O?

My computer is a laptop. CPU freq is in Dynamic mode. When these applications
are executed, CPU usage (system load, not user one) is heavy ; it grown up from
20% to approx. 100%. In process list, I see that wineserver CPU usage
corresponds with that heavy usage.

About disk I/O:
cat /proc/diskstats | grep 'sda5' before winecfg execution:
   8    5 sda5 111817 4343154 1902797 15222352
cat /proc/diskstats | grep 'sda5' when winecfg is displayed:
   8    5 sda5 111818 4343162 1906356 15250824
> Is everything slow? Even notepad and winecfg?

Yes, Notepad and winecfg are slow too.

I saw that even if applications are closed, wineserver is still running. I need
to execute "wineserver -k" to stop it.

You don't notice a slowdown with native Linux application because they
are not installed and being ran from the encrypted home.

Feel free to reopen this bug once there is a proof that native applications
do not slowdown when ran from an encrypted partition.

I solved my problem by creating a new .wine folder and coping all data from old
"drive_c" folder to the new one.

Now all application run correctly.
