Re: Image viewer gwenview needs 27 secs to start

Hi,

This needs some debugging of the application.

During these 27 seconds it can be interesting to get the output of:

procstat -kk <pid>
procstat -t <pid>

This shows if the application is waiting for the kernel.

Use 'top' to see if the application is running 100% CPU or not.
Use 'iostat -d -x 1' to see if it is waiting for IO.

Dtrace might also be useful to see what the application is doing, but I don't know the proper syntax from the top of my head.

Regards,
Ronald.
