Hello, I'd like to enlarge the test coverage of 286 to includes file mapping with repeated hole/unwritten/unwritten_without_data/data intersections. Those two new sub-tests could help verifying the current seek_data/seek_hole improvements. Besides, I observed a weird thing at the diff of 286.full, look at the the sparse file creation output, there seems to be a significant I/O degradation compare to the old test01/test02 IOPS results: -1 MiB, 256 ops; 0.0000 sec (1.242 GiB/sec and 325699.7455 ops/sec) +1 MiB, 256 ops; 0.0000 sec (70.161 MiB/sec and 17961.1310 ops/sec) I run the test on same machine and same partition, I recalled the old result is generated against around 3.4-rc2(not very sure), now is updated to 3.5-rc4, does anyone hit that?
Quick feedback. I don't see any degradation. OLD: 1 MiB, 256 ops; 0.0000 sec (484.027 MiB/sec and 123910.9390 ops/sec) THIS: 1 MiB, 256 ops; 0.0000 sec (494.560 MiB/sec and 126607.3195 ops/sec) All the tests are very close to the unpatched results.
