As usual, i was going to copy new files over wired network using ftp (to SD card)
Before the update, speed was at around 12MB/s, now it goes like 102MB/s (500MB from 0% to 100% in 4-5 seconds) - but the whole operation takes about the same time - it waits at 100% about a minute for the file complete.
During copiing, i saw a few APPE commands, and a few disconnects/reconnects.
