Hello everyone:
Recently, I did some testing with daos array interface, found that after finishing nvme bio, it took me a long time for writing metadata and resource release ; The total latency of single channel IO is about 80us, and vos_update_end taks about 30 us(about 17us in dkey akey update via SCM); I thought that IO via SCM should be very fast, but through the test, it's slower than the nvme IO. Is evtree operation takes too long or are there other reasons?
Best regards!
