SPIFFS upload time

I tried uploading SPIFFS files for the first time by using: Tools / Esp8266 Sketch Data Upload and I was surprised to see that it took more than 5 minutes to upload. I used the 3M SPIFFS option. Is this normal / expected? Can it be improved?

Upload from IDE transfers whole space (3M). At default baud rate 115200 that's maybe about 10kBsec. So 300 seconds which is what you see.
Options are:
use 1M SPIFFS if that is sufficient (third of the time)
use faster baud rate e.g. 512000
after first transfer use the ftp library to transfer running at wifi speeds

I have reliability issues with some of my setups. They can't all do 512K so I mostly use 256K. And as stated, using 1M is faster. I rarely need more than that space.

I must admit that I've never use Data upload, but I suspect that maybe an SPIFFS.format() is done on every uploads, which is always take time.
