    Default Dolphin Operations Slow Response

    Not sure if anyone else experiences this or not, did a search and did not find anything on it. I just updated my KDE from KDE 4.10.3 to 4.10.4. Dolphin has always been a bit sluggish but now it's much more pronounced. Example is if I'm in a folder with less than 100 files in it and I hover over a file and right click, the service menu takes at least 20 seconds to appear. It's pretty frustrating and slows down work flow tremendously.

    Does anyone else have this issue and is there a solution? I will provide whatever info I can to help resolve and toubleshoot. Thanks for any help.

    I have a machine that has half as good as specs as yours and I have never noticed any "sluggish" behavior from Dolphin. Clearly there is some problem with your setup.

    Have you check the output of "dmesg" for errors on bootup or some other hardware problems?

    So one aspect of Dolphins loading speed is its ability to read all mounted hard drive partitions and any network maps should you be using them. Are you mapping any Samba or other network drives? Why not give us a peek at your disks and the fstab file with these terminal commands, after you enter the password:

    Code:
    su -
    
    fdisk -l
    
    cat /etc/fstab
    
    df
    Just copy the results and post them into a message here using the advanced message text editor and enclose each text pasted in their own code # tag.

    Thank You,

    Hello,

    No, I do not have any samba running or NFS mounts and usually no external USB based drives attached. Here is the output requested: (Note: One thing I noticed after the update to 4.10.4 was that virtuoso was constantly running even when the indexer was not running and consuming 12-20% of CPU time constantly. I turned off indexing for Email only, and that eliminated that which improved speed of the system, and Dolphin, significantly.

    OMG Yes! That definitely helped. I also had the CTRL-A, right click massive delay issue and that is now gone with that plugin disabled. Thanks for pointing that one out too.

    Thanks everybody for the help and hints, definite improvement in speed of Dolphin. I'm still going to leave the Email Indexer OFF until the virtuoso issue gets resolved again. Seems like that keeps coming back around every so often.

    I know the issue is solved for now, but running
    Code:
    nepomukcleaner
    has been reported to "solve" heavy CPU loads of the indexing mechanism. It runs fine on my laptop, so I can't confirm the effect of running it.

    I am glad it resolved the problem
    Dolphin maintaner was quite unhappy (as you can see in the report) that "3rd party" plugin is making dolphin look bad.
    Wrt. indexing, with 4.11 it'll be quite unnoticeable, as i have experienced now with current trunk. Especially is email indexing silent now. (much slower, but i haven't even noticed, CPU wise, it's indexing my mails)
