bwlp/qemu.git/tests/perf, branch master Experimental fork of QEMU with video encoding patches https://git.openslx.org/bwlp/qemu.git/atom/tests/perf?h=master 2019-06-04T13:20:41+00:00 tests/perf: Test lseek influence on qcow2 block-status 2019-06-04T13:20:41+00:00 Vladimir Sementsov-Ogievskiy 2019-04-08T16:26:16+00:00 urn:sha1:52f2b8961409be834abaee5189bff2cc9e372851 Block layer may recursively check block_status in file child of qcow2, if qcow2 driver returned DATA. There are several test cases to check influence of lseek on block_status performance. To see real difference run on tmpfs. Tests originally created by Kevin, I just refactored and put them together into one executable file with simple output.
