Connecting with LAN

intro

2008-04-13 16:26:51

Hi ...

I am really sorry if someone else has just described it.

But I have one question. Why if I connect with LAN's computer by ftp or sftp transfers are so slowly?

Eg. file schould download/upload with eg. 2.5 MB/sec and not 100 kb/sec.

Thanks for any answer, Regards.

Take a look at this article:
https://www.smartftp.com/support/kb/how- ... f2558.html

You may need to change the buffer size.

Hi ...

I have done everything described in the article and I have changed buffer sizes. Now transfers are max 700 kb/s.

Sorry for this comparition, but with WinSCP I can transfer files with my max LAN speed (both via ftp and sftp).

What still can I do wrong?

Regards

mb

I have no idea. I can transfer with 10 MB/s here with the default settings.

2008-04-14 19:57:14

Just Thanks for trying to help. Regards.

mb

What did you set the buffer sizes too? Maybe you have to increase them even further. E.g. for the upload buffer try 128 kilobyte.

2008-04-14 21:14:17

For buffer sizes, receive/send/file I have set to max=262144.
Speed limits set to unlimited.

And no news here.

2008-04-14 21:23:24

Sorry ...

One update to my last post. Now for FTP connections there are max of LAN's speed. But still no news for SFTP.

mb

2008-04-14 21:47:50

I will look into SFTP. It has not optimized for LAN transfers yet.

Do you reach max speeds with WinSCP for SFTP transfers?

Mat

intro

2008-04-14 21:58:00

Hi ...

In fact ... transfer by WinSCP is between 2.5 and 3 MB/sec.

mb

2008-04-14 22:28:02

out of 10MB/s?

intro

2008-04-14 23:07:42

... now by ftp I can go with 9 - 10 MB/S, with sftp not

mb

2008-04-16 09:25:07

Please try it again with the latest version:
https://www.smartftp.com/download

It should fix the slow speeds with SFTP.

Mat

intro

2008-04-16 16:12:44

Hi ...

Unfortunately ... nothing new. But maby even slower it works now. What could be still wrong?

By WinSCP max speed is 3MB/s here.

Regards

mb

2008-04-16 16:53:53

Thanks for testing. I will look at it again.

Regards,

mb

Could you test the new version (.3) again? Sorry ;-)

Still we have no lucky. With newest (.3) version transfer has max 400 KB/s, previous was 700KB/s and previous (with max buffer size) about 900 KB/s.

Maby still I have something wrong set? But via LAN only SmartFTP is so slowly. Buffer sizes and speed limits are set to maximum. I have been trying with smaller, but nothing new.

mb

2008-04-17 09:01:49

I have only changed the buffers for upload in the latest version. Did you test uploading?

Regards,
mat

intro

2008-04-17 09:25:59

Yes, I was talking about upload. Download is a little faster.

mb

2008-04-17 09:26:00

Ha .. I have the horrible download speeds as well now. Upload speeds are fine though with the latest version.

intro

2008-04-17 09:43:40

So ... what I schould else check in my settings (or system's settings)?

mb

2008-04-17 09:56:30

Nothing really. It's a problem we need to fix.

mb

2008-04-17 11:46:23

New try:
https://www.smartftp.com/download

I have now the same or better speeds than WinSCP with almost any buffer size.

Regards,
Mat

intro

2008-04-17 12:27:28

I have no lucky

Download now is much better, between 2 and 3 MB/s, but upload no more than 400 KB/s.

mb

2008-04-17 12:30:44

I tested it with CoreFTP Mini Server on the server side:
http://www.coreftp.com/server/download/msftpsrvr.exe

Maybe you want to give it a try.

Hi ...

OK so now it looks like:

If I use provided by You small sftp server, then by WinSCP and SmartFTP I have transfers between 3 and 4 MB/s.

But my other servers are on linux and with WinSCP now i have transfers between 3 and 4 MB/s and by SmartFTP between 400 and 700 KB/s via download and about 400 KB/s via upload.

Regards

mb

2008-04-17 13:55:23

Did you run the Core Mini SFTP server on another box? Because you cannot run it on the same machine as SmartFTP is running because the situation is for some reasons totally different.

I will do some more tests with SmartFTP and OpenSSH running on another box.

Regards,
Mat

intro

2008-04-17 14:00:57

Yes Mat.

I was running those applications on other machines, becouse what sense would be testing anything here on the same box? Is any?

Regards

mb

2008-04-17 14:02:54

Well just want to be sure because I have initially tested it on the same machine and I got 30MB/s and as soon as I tested it in a virtual machine I got 300KB/s. And now it seems it even depends on the server software :-(

Regards,
Mat

mb

2008-04-17 14:41:50

I'm sorry but I have to disappoint you. I have tested upload/download speeds to a linux virtual machine running
[10:33:11] Starting SSH session. Remote Id: "SSH-2.0-OpenSSH_4.7"

and I get 10MB/s for upload and 4MB/s download. WinSCP gets 2MB/download and 5MB/s upload speeds.

Send Buffer: 32KB
Receive Buffer: 32KB
File Buffer: 32KB

intro

2008-04-17 16:28:23

So I have no idea :-| ... every sftp client has fast transfer and only SmartFTP not. By FTP all transfers now are fast, but with SFTP, not. I have checked many different settings. What could I have still wrong? What to check or change?

mb

2008-04-17 19:55:33

I have found other bugs related to this problem. Please test the new build:

Are you using openssh on your linux servers?

mb

2008-04-18 03:02:25

I have setup a linux box on another box in my LAN and I get better speeds (up to 100% faster) than WinSCP with the latest version. Please try it:

This is strange ... Now after this version I have notice that I need to upgrade to "Pro" version. I have Home, but I would like to do in next 12 days.

But ... so I will not test now it.

So in fact if this is not available, why I was able to use it earlier?

mb

2008-04-18 21:10:20

Hello ..

SFTP is not included in the Home version. However we allowed users and customers to use this feature for 2 months for free.

So no possibility to set this time 2 weeks longer? I will upgrade, but after 1 of May. So that mean my free 2 months away... I can not test anything more.

LOL ... Application crashed after that and I have lost all of configurations (and also all favorites). LOL. Nice. Thanks :-|

But in tranfers upload no more than 500KB/s now and download no more than 1.5MB/s now.

Btw. I have newest OpenSSH and for sure it has correct directives sets.

Regards

mb

2008-04-18 22:12:57

No the favorites do not get lost neither do the settings. Why don't you provide a crash report?

There is somethign wrong with your configuration. This thread is closed until somebody else experience similiar problems.

Just removed totally SmartFTP and all of SmartFTP system's registrys and installed it again and transfers are really very good. So why this could be the reason? :-|
But now it works good.

Also Favorites for lucky I see are saving as Favorites.old - it was simply to restore. So thanks
Uff.

So there is only one point left for my issues. As in my "Files are not displaying?" topic.

Regards and Respect
