John Kariuki c5840d77b3 test/bdev_perf: disable zcopy by default ... Prior to this patch the bdevperf application enabled using the zcopy API by default. This means that on bdevs that don't natively support zcopy the API emulates zero-copy by allocating a buffer. In my test environment, I measured a 25% decrease in IOPS when zcopy was enabled. This patch changes the default value so that zcopy is disabled by default. For bdevs that support zcopy, use the -Z flag to enable using zcopy API.
