Default Test with SQLIO
What is the default SQLIO test doing?
✍: FYIcenter.com
If you run the "sqlio" command without any options,
you are running the SQLIO default test, which is
equivalent to:
C:\fyicenter\SQLIO>sqlio -kR -t1 -s30 -f64 -b2 -i64 -BN testfile.dat
Let's try it out:
C:\fyicenter\SQLIO>sqlio sqlio v1.5.SG 1 thread reading for 30 secs from file testfile.dat using 2KB IOs over 128KB stripes with 64 IOs per run size of file testfile.dat needs to be: 8388608 bytes current file size: 0 bytes need to expand by: 8388608 bytes expanding testfile.dat ... done. initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 2995.43 MBs/sec: 5.85 C:\fyicenter\SQLIO>dir testfile.dat 8,388,608 testfile.dat
As you can see, the tool created a test data file, testfile.dat, of 8388608 bytes, in the current directory, C:\fyicenter\SQLIO. Then it performed a single thread reading test on this data file. The result is about 3000 IO blocks per second and 6 MB of data per second.
