USB CDC packet sending rate problem based on STM32F103

I used STM Cube to generate the USB CDC as a virtual serial port code, and then the test found that only a maximum of one thousand data packets can be sent to the PC every second. Is this fixed? Or is there any way to increase the data packet sending rate? Thank you~
