Azure Virtual HD on Windows 10 as C: - 64-KB Benchmark
What is the 64-KB I/O benchmark performance of Azure Virtual HD on Windows 10 as the system drive "C:"?
✍: FYIcenter.com
The I/O performance of reading and writing 64-KB files on an Azure Virtual HD on Windows 10 as the system drive "C:" can be measured by running SQLIO with multiple 64-KB blocks with a large stripe factor.
Here is the read performance test of Azure Virtual HD on Windows 10 as the system drive "C:" with 64-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kR -b64 -i64 -f64 -t1 -s30 -p0 using system counter for latency timings, 10000000 counts per second 1 thread reading for 60 secs from file test.dat using 64KB IOs over 4096KB stripes with 64 IOs per run affinity on cpu number 0 size of file test.dat needs to be: 268435456 bytes initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 7553.63 MBs/sec: 472.10 latency metrics: Min_Latency(ms): 0 Avg_Latency(ms): 0 Max_Latency(ms): 35 histogram: ms: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24+ %: 100 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Here is the write performance test of Azure Virtual HD on Windows 10 as the system drive "C:" on 64-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kW -b64 -i64 -f64 -t1 -s30 using system counter for latency timings, 10000000 counts per second 1 thread writing for 60 secs to file test.dat using 64KB IOs over 4096KB stripes with 64 IOs per run affinity on cpu number 0 initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 187.00 MBs/sec: 11.68 latency metrics: Min_Latency(ms): 3 Avg_Latency(ms): 4 Max_Latency(ms): 133 histogram: ms: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24+ %: 0 0 0 33 46 9 4 2 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 1
As you can see, in the simulation of multiple 64-KB file I/O, reading speed is 472.10 MBs/sec, and writing speed is 11.68 MBs/sec. So for a Azure Virtual HD on Windows 10, writing is about 40 times slower than reading.
