Hi

I tried to get top output in High signal strength, it shows that
during transfer

   21%               ksdioirqd/mmc1
   14%               adbd
   14%               wlan_main_service
   2%                system_server

these are taking much time.  Will these affect so significantly for UI
slowness?
is there any way to reduce time taken by these or only solution as
indicated by Howard.

Thanks
Gururaja B O
