how to reduce Latency of Send #64

Closed osdalong closed 1 year ago

osdalong commented 1 year ago

hi sirs.

I got a new development board， I found the Latency of Send is about 70ms on usb connection mode。 and the Latency of Send of quest2 is only 5-15ms

I had tested adb push on the development board。 push 12 G file into it, it cost 110s, speed is about 110MB/s. and push the same file to quest2. it cost 240s, speed is about 50MB/s. quest2 is slower than the board.

but why the Latency of Send of quest2 is faster than the development board's

I have checked the USBs on Windows 10 professional, they are all USB2.0。

Anybody can guide me how to reduce the Latency of Send of my development board.

I had found this issue about 3weeks ago, but cant reslove it.

on the board. it only can send about 500 packets every second. but on quest .it can send 7000 packets every second. 500 vs 7000. NOT 5000 vs 7000
