Default FlashFXP limitation to ~410 kb/s ???

Hi,

I have a really weird problem : when i download anything on FlashFXP (tested Linux ISO, .gz, etc...) my speed seems to be "locked" @ 410-420 kb/s

You can say "hmm maybe your DSL line cannot do more or the ftp is slow or you set download limitation in FlashFXP"
And i will answer "NO !!!"

Because i tested many things :
- Downloading with an other FTP Client : more than 600 kb/s for the same file & FTP (tested with 2 ftp/file) !!
- Modify some settings (include speed limitation) : same problem
- Reinstallating FlashFXP on an other directory to keep all default settings : same problem

Really incredible problem
Please help, i am new registered user and FlashFXP doesnt work as i wanted

* FlashFXP v3.02, build 1045, registered
* OS : WinXP Pro
* Running behind NAT/router [Yes] & Model [BEWAN 600]
* Running firewall [No]
* Running Antivirus [No]
* Network [xDSL 8 mb]

FlashFXP v3.0.2 doesn't have a download packet size option, you'll need to wait until the next release.

This is a known problem or what this 400 kb/s limitation ? I can't believe this is the only app limited @ 400 kb/s

Its not a known problem. Many people use FlashFXP on gigabit networks with great success. It has to be an issue with your internet connection and the packet size, etc.

Hi all,

I got this problem with FlashFxp too and I found how to resolve it.

- Edit your FlashFxp.ini

- Under [main] add

- RecvBuffer = 256

Ex:
[Main]
RecvBuffer = 256
..
...
.....

You should get a higher speed. It works for me.


Hope this help nd please let me know if it works.

Thank you for your answer.

I tried but it doesnt work, i don't get more high speed, i tried with 16, 256, 512

Maybe it's for an older version ? I have the last one (3.0.2)


EDIT : And this happened ONLY in FlashFXP, i didn't see any apps that limit my speed, even other FTP Client in PASSIVE Mode

I discovered an important thing !!!

The speed limitation problem appears ONLY in PASSIVE MODE, i am stuck @ 400 kB/s or around 500 kB/s

In ACTIVE MODE, i am at FULL SPEED, for my ADSL LINE = 8 mb/s = 1 MB/s

I hope it will help dev(s)

Ok thanks, but no fix yet
And i agree with others it is a FlashFXP problem, coz SmartFTP handle this correctly
Maybe a UPNP support will correct this weird problem ? Who knows

Your right, I haven't been able to figure it out and since I can't reproduce the problem on any of my machines it makes this very difficult to solve.

Some people have reported that FlashFXP v2.x doesn't have this problem but the underlaying transport routines for v3.x are almost identical and the changes that were made do not appear to be causing this problem.

UPNP would effect incoming connections (PORT) and you are experiencing this problem with outgoing connections (PASV).

Copy/past PORT code on PASV code, even if it is the same
I know we often say "it's same", but a small change can **** up an entire algo

And release a new private BETA, so we can test it

This has already been done, Using the old code caused the same slower than expected results. It didn't make any sense what-so-ever. BTW I replaced the entire ftp engine, not just the PASV/PORT routines.
