7. Write it later:
It took a lot of effort to finish the test.
After doing it, my heart became a little heavy.
Judging from the test data, the technology of domestic upload components is obviously not on the same level compared to foreign upload components. Most of the domestic upload components are free to use, and are the simplest way to read binary data for uploading. There is no technical breakthrough. It is OK when uploading small files. When uploading large files, the upload speed has dropped sharply, and the general CPU occupancy rate is extremely high, generally 100% of the CPU occupancy rate of the whole process; while foreign upload components have formed an industry. Except for the components that are free to be used in .net environments, the other two are paid (the usage fee of aspupload3 component is as high as US$500). In terms of technology, some unknown data reading method is adopted, which greatly improves the upload speed. Especially when uploading super large files, it greatly reduces the occupancy rate of the server CPU, reducing the CPU occupancy rate to an astonishing level of 30%, and the upload speed is as high as 1M/s (almost the same as the flash disk speed). These are incomparable to domestic upload components.
In addition, this test is carried out in the environment of a local area network, and the data transmission rate is obtained is relatively high. However, since the key point of the test is not to conduct quantitative tests, but to compare the performance between each upload component, the transmission rate is not important. What is important is the performance comparison between them and the extent of the server CPU. If any friend has different opinions, please feel free to discuss it together.
8. What kind of upload component is suitable for me?

Components

Suitable for any situation, but only if you can use technology. It is recommended that those with conditions go to all.
|
|
Aspupload3.0 component
|
The speed and CPU occupancy rate are extremely excellent. If you cannot use technology, it is recommended that those with wealthy go first.
|
|
FileupV4.01 Components
|
The same as above is worse than the aspupload3 component, but it is also sold for money. It can be seen that it is too fat. It is recommended that those with richness are not as good as those with aspupload3 component.

Lyfupload1.2B component

If you don't use broadband and are not on the LAN, and the server provider allows you to use this component, and you don't seem to be very rich, just go! But I'm afraid there are not many such opportunities.

Liang Wuyu has no component upload class
|
If you are neither using broadband nor in a LAN, and the server provider does not allow you to use components, and you have no money in your pocket, you have to go to this one.
|
|
No component upload class in the realm
|
It is highly recommended not to go on it.
|
What if there are other cases that are not included? ...(This, this, you can find a way.)
