VM upload speed using rdp is very slow

Question

Hi,

I currently have a Standard B4ms vm on East US region running Windows Server 2019. The setup for RDS is the typical one, using a gateway. The problem I have is while trying to copy a file to the vm through the remote desktop client. Download speeds are very good. I have tried several RD clients, in general, the problem is the same: slow upload speed. Also, the machine tends to "freeze" while copying. As a reference, a 1mb file takes more than 20-30s to be transfered.

I have tried replicating the situation without using the gateway and it is still very slow.

I hope someone has been in a similar situation and could provide me with some guidance to solve this problem.

Thanks in advance.

Hi,

Did you check the Network throughput of that VM? https://learn.microsoft.com/en-us/azure/virtual-network/virtual-machine-network-throughput

Also try NTTCP tool to verify the download and upload speeds-https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-bandwidth-testing

BTW -B Series is specific to development and test servers, low-traffic web servers, small databases, micro services, servers for proof of concepts and build servers.

Also try to optimise the Network components on the VM and see if it makes any difference.

Hope this helps.

Hello Fernando Garza

Welcome to Microsoft Q&A Platform, thanks for posting your query here.

Adding to previous response from Marshaljs, slow upload speeds could be caused by network issues on your end. It's also worth noting that RDP is not designed for high-speed file transfers, and other factors, such as the size and number of files you're transferring, can impact transfer speeds.

You can also try below troubleshooting steps and see if it helps solve your issue:

The B4ms VM size is designed for applications with lower CPU requirements. If you are trying to copy large files, consider upgrading to a larger VM size that can handle the workload.

Make sure you're using the latest version of the RDP client, and try adjusting the display and connection settings to see if that improves performance.

Consider using a different file transfer method, such as FTP or SFTP, which are designed for faster file transfers over the internet.

Hope this helps.
