To see the data read performance with the SELECT statement with a MEMORY_OPTIMIZED table
on SQL Server 2016, you can run the SQL script, fyi_select_in_memory.sql, presented in the last tutorial
with different @Count and @Size.
The following table shows the summary of the test results. Some fields are removed to save space. additional fields are added with calculations on existing fields.
@@version = Microsoft SQL Server 2016 - 13.0.5292.0 (X64) Size Count Duration Bytes Throughput MB/s 256 100 0 25600 256 500 16 128000 7.63 256 1000 16 256000 15.26 256 5000 76 1280000 16.06 256 10000 173 2560000 14.11 512 10000 186 5040000 25.84 1024 10000 156 10160000 62.11 2048 10000 170 20480000 114.89 4096 10000 170 40960000 229.78 8192 10000 203 81840000 384.48 16384 10000 203 163760000 769.33 32768 10000 250 327680000 1,250.00 32768 20000 470 655360000 1,329.79 32768 50000 1216 1638400000 1,284.95 32768 100000 2530 3276800000 1,235.18 32768 500000 14190 16384000000 1,101.13
As you can see the peak throughput of reading data, 1,329.79 MB/s reached at @Size=32768 and @Count=20000.
