Considering all the other factor same for both the configuration, yes small configuration 
would take less time. To read good copies, it will take less time. 

I think, multi threaded shd is the only enhancement in near future.

Subject: [Gluster-users] ec heal questions 


Assume we have 8+2 and 16+4 ec configurations and we just replaced a 
broken disk in each configuration which has 100GB of data. In which 
case heal completes faster? Does heal speed has anything related with 
ec configuration? 

Assume we are in 16+4 ec configuration. When heal starts it reads 16 
chunks from other bricks recompute our chunks and writes it to just 
replaced disk. Am I correct? 

If above assumption is true then small ec configurations heals faster right? 

Is there any improvements in 3.7.14+ that makes ec heal faster?(Other 
than multi-thread shd for ec)
