{

NThreads: <n>, // number of threads (default 1)
FileSizeMB: <n>, // test file size (default 1 MB)
SleepMicros: <n>, // pause for sleepMicros/nThreads between each operation (default 0)
Mmf: <bool>, // if true do I/o's via memory mapped files (default false)
R: <bool>, // do reads (default false)
W: <bool>, // do writes (default false)
RecSizeKB: <n>, // size of each write (default 4KB)
SyncDelay: <n> // secs between fsyncs, like -- syncdelay in synchronized D. (default 0/never)
}
Test:
[Root @ php1 ~] # Cat <jsonfile
{
NThreads: 1,
FileSizeMB: 1,
SleepMicros: 0,
Mmf: 'true ',
