I recently increased the port speed on my VM but it is still performing very slowly.
OnApp Cloud (All Versions)
When changes are made to the networking of a virtual server, the changes must be applied to the virtual servers networking configuration using the Rebuild Network tool.
In order for the new port speed to take effect you need to rebuild the network on the VM using the "Rebuild Network" tool in the Virtual Server page in your OnApp UI. When you do this please be sure to use the "Force Reboot" option as it is necessary to stop the vm completely and then turn it back on. This will be done by the system automatically when the Force Reboot option is selected.
This will refresh the network settings to reflect the change you made, and the speed will be at what you recently changed it to.
