File transfers over network

[DarkEnergy]

I'm trying to figure out how this works and why there's such a difference. My setup has my main rig on ethernet and my laptop is on wifi. Using a program called Dukto on both computers, I'm transferring ~22gb of jpegs to my laptop. When my laptop is near the router I'm getting ~150mbps transfer speed and upstairs it drops to ~120mbps. If I run an internet speed test at the same time I get a total of ~170mbps with speedtest.net showing ~70mbps (internet speed) meaning the file transfer speed must have dropped. BUT, if it's able to reach ~170mbps during the internet speed test, why can't just transferring files reach that too? SSD/HDD is not bottlenecking. I figured it must just be the fact that it's a lot of jpegs, buuuuut I also have a program on both computers called synthing that syncs picture folders and when I run that program, I've seen it transfer png/jpg files over the network at ~350mbps. What gives?

It could just as well simply be Dukto itself which is inefficient.

Anything you'd recommend instead of dukto?

Sorry, I don't use anything such as you do and as such I don't know any applicable apps. I have a NAS and a USB SSD for copying files around with, myself.

Why not just use the smb sharing built into windows.

Moving many small files is slower than moving few large files.  There's a 'start' and 'stop' for each individual file and it costs overall transfer speed.

If you mean folder sharing and whatnot, it's a steaming pile of crap that windows tries to make more complicated. I've had issues with it in the past.

I wouldn't call it a pile of crap. Its well supported, fast and on basically every system out there. And its pretty darn stable too.
