Thanks for your report! I would guess that the download speed is slower than the rate at which data is added to the memory buffer. Since writing the data to memory works well for most users who don't download tens of thousands of files, we could add a setting or size threshold that writes the data to disk and streams it from there instead. However, note that you might run out of disk space in this case. Would you like us to implement such a solution? Do you have any preferences?

将数据写入磁盘并从磁盘流式传输。不过请注意，这种情况下你可能会用尽磁盘空间

I think there's no problem, after all, the cost of adding a hard drive is relatively cheap.
