@ironfede Just for a quick check for perf/memory usage improvements so far: v2.3.1.0 | Method | BufferSize | TotalStreamSize | Mean | Error | StdDev | Gen0 | Gen1 | Gen2 | Allocated | |------- |----------- |---------------- |------------:|----------:|----------:|----------:|---------:|---------:|----------:| | Test | 1048576 | 1048576 | 187.9 us | 3.71 us | 8.14 us | 137.6953 | 68.6035 | - | 1.1 MB | | Test | 524288 | 1048576 | 196.9 us | 3.85 us | 5.39 us | 140.1367 | 55.1758 | - | 1.12 MB | | Test | 262144 | 1048576 | 219.8 us | 2.81 us | 2.76 us | 144.2871 | 72.0215 | - | 1.15 MB | | Test | 131072 | 1048576 | 276.2 us | 5.04 us | 4.47 us | 152.8320 | 76.1719 | - | 1.22 MB | | Test | 4096 | 1048576 | 3,899.4 us | 74.65 us | 69.83 us | 671.8750 | 335.9375 | - | 5.41 MB | | Test | 1024 | 1048576 | 15,455.3 us | 141.46 us | 125.40 us | 2281.2500 | 375.0000 | 156.2500 | 18.37 MB | | Test | 512 | 1048576 | 30,795.2 us | 614.23 us | 880.90 us | 4468.7500 | 437.5000 | 187.5000 | 35.66 MB | visionaid/memory | Method | BufferSize | TotalStreamSize | Mean | Error | StdDev | Median | Gen0 | Gen1 | Gen2 | Allocated | |------- |----------- |---------------- |------------:|----------:|----------:|------------:|----------:|---------:|---------:|----------:| | Test | 1048576 | 1048576 | 143.1 us | 2.58 us | 2.41 us | 143.0 us | 137.2070 | 58.8379 | - | 1.1 MB | | Test | 524288 | 1048576 | 152.8 us | 2.85 us | 2.93 us | 153.1 us | 139.1602 | 57.1289 | - | 1.11 MB | | Test | 262144 | 1048576 | 177.9 us | 3.40 us | 2.84 us | 178.4 us | 143.5547 | 71.7773 | - | 1.15 MB | | Test | 131072 | 1048576 | 223.3 us | 4.42 us | 6.20 us | 220.7 us | 151.8555 | 75.9277 | - | 1.21 MB | | Test | 4096 | 1048576 | 2,846.8 us | 52.94 us | 46.93 us | 2,832.3 us | 675.7813 | 335.9375 | - | 5.4 MB | | Test | 1024 | 1048576 | 11,435.8 us | 225.95 us | 476.61 us | 11,243.3 us | 2296.8750 | 375.0000 | 140.6250 | 18.35 MB | | Test | 512 | 1048576 | 21,693.7 us | 263.82 us | 246.78 us | 21,761.8 us | 4437.5000 | 343.7500 | 156.2500 | 35.63 MB | For small buffers, I find performance is improved ~30% or so since v2.3.1. Not too shabby! I reckon I can get the memory usage right down after the next round of changes are merged :) |
