Hello, 

I have some problems about glusterfs's lock mechanism. what is glusterfs's lock mechanism ? How does it works?  using  iozone tool to test its  the performance of  read and write, i find small write in lock state is as ten times as in unlock state,so i want to know why.

 

Experimental figure in the attachment.

Thanks for your attention.

Yours sincerely,

Aihua Shen
