I am using a raspberry pi with samba as remotely accessible storage in my local network. While copying files from windows to pi I am getting strange transfer speed. It jumps from 200 kB/s and less to 10 MB/s. It always stays for about 2 seconds at the low speed, then for the same time at the high speed.
Anyone has in mind what could be the cause? Bad USB flash drive, badly configured samba or is it just showing inaccurate speed because copying to different file system?
