☆ Percentage of MEMORY Usage
Upload components usually use the Request.BinaryRead() method, except for the component uses method in PostFile Class that is provided by .NET Framework. However, in real circumstances, there was not a big difference in memory usage for using either method of implementation. The only difference occurred when using PostFile Class which showed intensive memory increase for large upload files due to it’s use of the whole file in loading. Generally, the following results were recorded.
1) Size of Uploaded file : 56MB ; Memory Usage : about 60MB
2) Size of Uploaded file : 137MB : Memory Usage : about 200MB
3) If the memory size is 512MB and you are uploading files greater than 137MB, then the uploading in .NET
Runtime is cancelled because the oversize file limit.

☆ Upload TIME(Speed)
DEXTUpload.NET Pro. was internally tested as the fastest in upload speed.
