The issue you are seeing is a little complex one but information you have provided is very less. 
- Volume info 
- Volume status? 
- What kind of IO is going on? 
- Any brick is down or not? 
- Snapshot of Top command. 
- Anything you are seeing in glustershd or mount logs or bricks logs?

Hi Team, 

Whenever I am performing the IO operation on gluster volume, the loads is getting increase on CPU which reaches upto 70-80 sometimes. 

when we started debugging, found that the io_worker thread is created to server the IO request and consume high CPU till that request gets completed. 

Could you please let me know why io_worker thread takes this much of CPU. 

Is there any way to resole this?
