High io usage by jbd2/sda2-8

I am experiencing high io usage by jbd while running my python test utility which constantly talks to sqlitedb which results in high io wait time. How should I resolve the issue?

It consumes 99% of IO even while it's not writing to disk!!

Alternative could be to increase time for flushing to disk by adding commit=nrsec to /etc/fstab where nrsec should be higher than default 5 seconds.

Caused by journalling block device which takes high amount of I/O usage whenever I run my modules, disabling it using tune2fs utility solved the problem.
