Transfer from DRL: Obtain the upload speed from flashfxp

In the flashfxp option => advanced, there is an option called upload packet size, which controls the size of the uploaded package.
This setting greatly affects the upload speed.

3. The default value of X is 4 K, and the maximum value is 16 K.
OK. Let me test it.

My Nic is Intel pro100/ve, and the network is m exclusive to China Telecom
In Guangdong, the FTP uploaded is located in the Shanghai Telecom data center and exclusive to 1 GB.
Why not select local FTP? Because I am connected to the province, as long as the other party's bandwidth permits, the speed is above 10 Mb/s ....

Test start:
The default size is 4 K packet. the upload speed is 200 K/s, which is really slow.
It is set to 16 K, the maximum upload speed is 800 K/s, and the average speed is 737 K/S... it seems to be a qualitative improvement.
...

It is found that the packet size exceeding 16 K cannot be set on the ffxp Interface
Open flashfxp. ini and find UTB. this parameter is the setting of upload packet size.
Package size = 2 ^ (UTB-1)
Set
UTB 19 is 256 K
UTB 18 is 128 K
....

The size of the test is 32 KB. the upload speed ranges from 840 K/s to 770 K/s on average.
Test 64 K size, upload speed up to 860 K/s, average 790 K/s
Test the size of 128 kb. The maximum upload speed is 930 kb/s, and the average uploading speed is 870 kb/s.
Test the size of 256 kb. The maximum upload speed is 980 kb/s, and the average uploading speed is 890 kb/s.
......

By 256 kb, it is found that the upload speed is not very stable.
Manually set UTB, And the ffxp option will be blank

The size of the K package is determined.

Please do not set UTB blindly and use it based on your actual situation.

Ftprush supports uploading and downloading, and changes the global settings. The site manager uses the global settings by default.
You can set it by yourself. F6-transfer-change the buffer size
