Virtual HD ATA Device on Server 2016 - 1-MB Benchmark
What is the 1-MB I/O performance of Virtual HD ATA Device on Azure VM?
✍: FYIcenter.com
The I/O performance of reading and writing 1-MB files of a Virtual HD ATA Device can be measured by running SQLIO with multiple 1024-KB blocks with a large stripe factor.
Here is the read performance test of Virtual HD ATA Device on Azure VM with 1024-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kR -b1024 -i64 -f64 -t1 -s30 -p0 1 thread reading for 300 secs from file testfile.dat using 1024KB IOs over 65536KB stripes with 64 IOs per run affinity on cpu number 0 size of file testfile.dat needs to be: 4294967296 bytes current file size: 268435456 bytes need to expand by: 4026531840 bytes expanding testfile.dat ... done. initialization done CUMULATIVE DATA: throughput metrics: IOs/sec: 420.06 MBs/sec: 420.06 latency metrics: Min_Latency(ms): 0 Avg_Latency(ms): 1 Max_Latency(ms): 1027 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+ %: 75 19 3 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2
Here is the write performance test of Virtual HD ATA Device on Azure VM on 64-KB blocks.
C:\fyicenter\SQLIO>sqlio -LS -kW -b1024 -i64 -f64 -t1 -s30 1 thread writing for 300 secs to file testfile.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: 39.48 MBs/sec: 39.48 latency metrics: Min_Latency(ms): 13 Avg_Latency(ms): 24 Max_Latency(ms): 421 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 0 1 8 17 18 15 11 7 4 3 2 1 13
Reading/writing speeds of 1-MB blocks, 420.06/39.48 MBs/sec, are much higher than reading/writing speeds of 64-KB blocks, 232.13/12.43 MBs/sec.
