13
14              : Checks writing/reading performance in sequence.
15
16              tkrzw_file_perf wicked [options] path
17
18              : Checks consistency with various operations.
19
20   Common options:
21       --file  impl  :  The  name  of  a  file implementation: std, mmap-para,

23
24       --iter num : The number of iterations. (default: 10000)
25
26       --size num : The size of each record. (default: 100)
27
28       --threads num : The number of threads. (default: 1)
29
30       --random_seed num : The random seed or nagative for real RNG. (default:

32
33       --alloc_init num : The initial allocation size. (default: 1048576)
34
35       --alloc_inc num : The allocation increment factor. (default: 2.0)
36
37       --block_size  num  : The block size of the positional access file. (de‐
38              fault: 1)
39
40       --head_buffer num : The head buffer size of the positional access file.
41              (default: 0)
42
43       --direct_io  :  Enables  the direct I/O option of the positional access
44              file.
45
46       --sync_io : Enables the synchronous I/O option of the positional access
47              file.
48
49       --padding : Enables padding at the end of the file.
50
51       --pagecache : Enables the mini page cache in the process.
52
53   Options for the sequence subcommand:
54       --random : Uses random offsets rather than pre-defined ones.
55
56       --append : Uses appending offsets rather than pre-defined ones.
