Hi,
version : 5.3.1

Some test on using FTP upload indicates very slow upload compared to all other clients tested with same file to same server. Any suggestions?

Hi,

VisualCron uploads files sequentially. Other clients may upload many files at a time. What you can do, if you have many files, is to create two Tasks that run at the same time but uploading to different folders.

Hi,

This test is done with one file only, one large file, 7MB uploaded to a server sitting behind a ADSL connection. Uploading with FileZilla or ftp.exe takes 15 sec. , but VC uses + 60 secs ?????

OK, I see. The problem can be that we are using a fixed buffer. In your case a bigger buffer should be faster. I am moving this post to feature requests and we will either make a dynamic buffer or letting you set that value.

Is it possible to bump this? It seems that the performance of the ftp implementation
is extremly slow om large files compared to all other clients! Maybe it should be classified more as a bug?😕

Hi Svein,

did not notice first that you were using an ADSL connection.

We tried upload in our network and the speed was ~7 MB/s. We transferred one file, 124 MB, in 18 seconds. We were also using SSL which slowed it down a bit. So we do not see any performance problem with sending one file over a fast network.

So the questions for you are:

1. are you sending many files?
2. Is the target folder empty? If not, can you try sending a file to an empty target folder?
3. what other ftp settings do you use?
