Why memory read speed is much slower than memory write speed？

>dump_image test1.bin 0xffffffff80003e3e 1048576
dumped 1048576 bytes in 42.666645s (24.000 KiB/s)
>load_image test1.bin 0xffffffff80003e3e
downloaded 1048576 bytes in 10.778667s (95.002 KiB/s)

I conducted a memory block read and write test and found that the memory read speed is relatively slow. Why is that?

Might be worth capturing and attaching (not copying and pasting) a verbose -d3 log for the two scenarios for comparison?

The logs have been attached, thank you.
