Description
After landing LU-9906 the read performance improved to an acceptable level. Write performance also increased but still needs some improvements to reach the same level. This ticket tracks the work.
As we can see
LU-9920can reduce the overhead in set_page_dirty/write_commit_callback.There is still __ _raw_spin_lock from osc_page_cache_add which I can not figure out the exact location.
