Is XenServer limiting download/upload rates?

DReade83 used Ask the Experts™
I have a XenServer installation with CentOS 5.4 installed. When uploading to the CentOS VM via Secure FTP the upload rate is fixed to 500KB/s and the download to 1MB/s.

Is XenServer doing this? Does anyone know anything I can try?

I already posted this question in the Linux section thinking it was CentOS doing it, but I was asked to look at XS instead that could be causing this issue.

Any help appreciated. Thanks in advance.

Is your traffic going via an ISP, or is it completely internal?


100% internal, via a Gigabit wired network.
Is the virtual machine paravirtualized?
To  be that is should have Xentools installed.
OK just done another test by uploading a 2GB file to normal FTP. Upload/download speed of 50MB/s. So it seems to be a secure FTP thing after all.
