Hi, perf users and developers 

I have several questions about perfconfig

1. [colors] section : What is concrete evaluation standard of ’top’ and 
‘medium’ ?
( I've thought  that ’top’ and ‘medium’ is decided by CPU overhead(%) but I 
don’t know it’s more concrete standard  )

2. [colors] section : Why is it that the name which decide colors of line for 
jumping with assemble command such as ‘jmpq’ is ‘code ‘ ?  

3. [colors] section : What would you think  ‘headers’ is better than ‘root’ ?
(Because ’show-headers’ which [ui] section has decide whether column names on 
the top of output is shown or not.)

4. [call-graph] section : Is it a bug that after 'sort-key’ is set ‘address’ if 
I select shared object and  symbol such as “ [kernel] , [k] vfs_read “
, perf process is stopped with error message ‘addr2line: /proc/kcore: File 
format not recognized’ ? 


Thanks, 
Taeung
