Ubuntu 14.04 LTS network performance problem on vmware ESXi 5.5

[cygus]

Hi,

I have problem with Ubuntu 14.04 LTS and network performance (ESXi 5.5). After starting downloading file (http/scp etc.) transfer is ok but after about 2-3s. transfer is going down to 0. I checked everything with virtual eth adapters (e1000 and vxnet3) and with vmware tools (vmware-tools and open-vm-tools).

This problem exists with transfer file to Internet, when I transfer file inside our network everything is ok.
On physical servers, openvz and vmware 5.1 servers everything is ok.
This problem is only on vmware 5.5 with ubuntu 14.04 as guest OS, so this is problem with ubuntu.

Who can help me?

We are using standard packages here so yes it may be related to ubuntu drivers there.

Ok, but maybe you can help to fix this problem?
For example this same problem exists on ubuntu 12.04 but on Debian 6/7 deosn't exist.

How I can fix something I didn't test? Or had the issue?

Also this is low level, as we focus more on front end and sysadmin.

You may get more help on Ubuntu forums.
