It's not just a trust issue, it's looking to see if *I* screwed something up!

When I move a folder, I see the entire folder contents (all the files) in the deleted section and again in the new files section.

I love FFS, and use it all the time. There's really only one thing that has always bugged me about the application and that's the way it handles moved folders.

Moved folders show up as deleted folders and new folders. It's hard to match them up to make sure that nothing has gone wrong in the ...

> So 3.20 is actually faster in your tests now??

Yeah...it's weird. The day I posted the issue it was well on its way to a 4
hour compare. Then it did 16:48 a couple days later with no changes other than
installing 3.16 (which I agree should have nothing to do with anything). Like
I said, I'll ...

Okay 3.16 (from before, not today) about 670,000 elements 36:32, 3.20 - 16:48
(for compare only). That one odd folder with all the subfolders paces
everything.

Okay...I figured out the parallel install thing but I couldn't get 3.16 to
scan at all (hit compare, screen flashes, that's it). Odd.

So then I went to time 3.20 and.....it's running at normal speed now! What the
heck? Could installing 3.16 separately have had any effect on anything? I
don't see ...

I'm not sure how to do a parallel install so I'll answer what I know now
instead.

On 3.16 (I never had .19 installed), I had the same config file reading four
local folders and the corresponding four on another machine over wireless N
networking. This particular folder (one of the four on the ...

Hmmm...not so sure now. I'm having a little trouble. Scanning one of my
folders over the Gigabit network is at least one whole order of magnitude
slower than it was in .13 - possibly as much as 2 orders of magnitude over
wireless (300Mbps wireless N) on that same folder. Oddly the other folders
seem ...

Thanks for implementing this! It seems to work!

Thank you!

Also, it's not just source and target, since we can use many sources and many
targets. It would be nice to start many sources at the same time and many
targets at the same time provided they are all on different volumes.

Thanks again!

A possible idea for faster scanning:

If multiple volumes are to be scanned, start processes to scan each unique
volume all at the same time. I'm currently scanning 7 different volumes, and
FFS does them all sequentially. Since the scan takes around half-an-hour, a
significant savings could be had ...

Yes, I think it's odd too. However, it's not two users. There is only one
wireless link and only two computers. All I do is add another instance of the
app and both speed up. In fact, if one instance is FFS and I add an instance
of the other app, FFS speeds up (a lot) when the other app starts ...

It's not from the cache, I don't think. I've done full-system cold starts and
still seen this effect on the first launch. Also, if I am in the middle of a
sync and launch another one (using a different tool) the first one
dramatically speeds up as soon as the other one starts interrogating the other ...

Found an interesting thing regarding performance, not just with lots of folder
but with lots of files too.

If you have two folders to sync, each with lots of files, and you're doing
them on a slow link (i.e. wireless), comparing them simultaneously will make
both complete faster than either one ...

Thanks for the response. If you have a test case (application/exe) you'd like
for me to run, I have a situation where I have approximately 95,000 files in
about 1,200 folders, and also another location with about 85,000 files in
approximately 50,000 folders. This is all on XP. Just doing windows ...

The performance of FFS with lots of files is quite impressive. It's less
impressive with lots of folders. I use an application that (unfortunately) can
create tens of thousands of folders, each with 1 or 2 files. This slows down
FFS by more than an order of magnitude compared with syncing the same ...
