General issue report

I need to send multiple bytes cyclically using esp32 s3 spi, I found that even if I don't add a delay, the data interval between each sent byte is very long (15us), I've tried to set the cpu frequency to 240M, is there any way I can regulate this interval, please give me a little guidance, thanks! 我需要使用esp32 s3的spi循环发送多个字节，我发现即使我没有添加延时，每个发送字节之间的数据间隔也很长(15us)，我已经尝试把cpu频率设置为240M，有什么办法可以调节这个时间间隔吗，请给我一点指导，谢谢。

Queue the bytes before committing the transaction. Change .length = 8 to .length = 32 and see what happens.
