Azure Virtual HD on Windows 10 as C: - 1-MB Benchmark
What is the 1-MB I/O performance of Azure Virtual HD on Windows 10 as the system drive "C:"?
✍: FYIcenter.com
The I/O performance of reading and writing 1-MB files of a Azure Virtual HD on Windows 10 as the system drive "C:" can be measured by running SQLIO with multiple 1024-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 1024-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kR -b1024 -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 1024KB IOs over 65536KB stripes with 64 IOs per run affinity on cpu number 0 size of file test.dat needs to be: 4294967296 bytes initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 35.22 MBs/sec: 35.22 latency metrics: Min_Latency(ms): 0 Avg_Latency(ms): 27 Max_Latency(ms): 3020 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+ %: 17 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 8 15 16 12 8 5 3 2 13
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 -b1024 -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 1024KB IOs over 65536KB stripes with 64 IOs per run affinity on cpu number 0 initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 23.77 MBs/sec: 23.77 latency metrics: Min_Latency(ms): 11 Avg_Latency(ms): 41 Max_Latency(ms): 3554 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 0 0 0 0 0 0 0 0 0 3 11 13 11 7 8 7 4 2 2 1 1 29
Reading speed of 1-MB blocks, 35.22 MBs/sec, is slower than reading speeds of 64-KB blocks, 472.10 MBs/sec. But writing speed of 1-MB blocks, 23.77 MBs/sec, is faster than writing speeds of 64-KB blocks, 11.68 MBs/sec.
