Hi,

I am working with SLES12 and KDE and have some problem with its performance. After some time of using my servers desktop starts freezing for some time. This 'hanging' state holds for a few seconds where you can not interact at all. It is possible to move the cursor but thre is no reaction to any clicking action. After a few seconds you can continue working (sometimes it takes a few minutes). To find out more about this behaviour I did some monitoring and testing.

I found out that the hanging session doesn┤t affect any other running session. So I was able to create the hanging state while monitoring the system. During the hanging state there is no process that has a big CPU or RAM utilization. The only noticable parameter is the I/O utilization which is a bit higher than normal. The slightly higher I/O utilization was raised by the usage of a virtual machine or by copying big files. My suggestion is that it has something to do with I/O but I was not able to find any appropriate solution. I tried different I/O Schedulers and I used different kernels (default and desktop) but it didn┤t help at all.

Does anyone have similar problems while using SLES 12? Or anyone have an idea what can cause these behaviour?

Information about my system:
HP DESK800 G1 (8 i7 cores and 16 GB RAM)
SLES 12
KDE 4.14.9
Kernel: 3.12.39-47.2-default/desktop

System messages during a hanging state:

Hi,
I am having the same problems which you have encountered. I moved from sles11sp3 running 5 vm's under kvm (32GB ram with 8core cpu), and get the same hanging for a number of seconds even when no vm's are loaded. I have tried this on 2 servers with the same results, and have reached a stage where I am going back to SLES11Sp4 as the kvm server. I have also noticed that the vm's run much quicker on SLES11, and GNOME desktop under 12 is an absolute pain. My advice is to use SLES11SP4 rather than SLES12, as it works as you would expect, and there are no apparent issues with performance and changed modules. Another example is the iSCSI on 12 gives multiple logins for the initiator for no apparent reasons, whereas 11 works flawlessly.

Cheers,

ChasR.

was raised by the usage of a virtual machine or by copying big files. My

find any appropriate solution. I tried different I/O Schedulers and I
used different kernels (default and desktop) but it didn_t help at all.


Does anyone have similar problems while using SLES 12? Or anyone have an
idea what can cause these behaviour?
