GNS3 with VMware workstation and 2 VMs, getting really slow bandwidth between VMs

Hey all,

Need some help on this one. Im running GNS3 with a cisco switch and two VMs on workstation. I connected the two VMs to the same switch and gave them each an IP. I am able to ping between the two and SSH as well. (linux boxes).

This all started when I tried doing wireshark training and got wireshark to open in one VM but do processing on the other - kinda like a raspberry pi running on site and then be able to open it over a terminal.

Anyway, i noticed it was really slow. I started iperf on them and Im only getting barely 2Mbps between them.

What should I start looking in to?
