How to improve the write performance of custom engines

I got a strange phenomenon that when I ran the customer storage engine EXAMPLE with ycsb 100% write workload, only 30~40% cpu would be used. But 100% of the cpu would be used with ycsb 100% read workload. You know, there is nothing implemented in EXAMPLE. So what's the difference between read and write in mysql? Why thoes things would be happend? By the way, I also had a test on INNODB, 60%~70% of the CPU would be used with ycsb 100% write workload. I would be very grateful if you can answer my question!
