Bottleneck in my HomeLab

I recently rebuilt my plex media server inside a VM. I was transferring several media files and noticed that the throughput peaks at 10MB/s and averages to about 7.6MB/s.

The source computer is older and only have 10/100Mb/s network interface while the destination computer is my ESXi server that has a 1Gb/s network interface. Both are connected by D-LINK DIR-615 which also maxes at 100Mb/s.

I need to access my Vcenter Server remotely as from time to time I practice on my homelab even if I am not at home. The easiest method I did before was punching holes in my firewall by port forwarding. I know this is not the most secure and practical way, but the concepts are easy enough for me to understand.

Accessing Files in Android Phones using Linux

From time to time I need to plug-in my Android phone to my computer to be able to transfer files.

Usually what I do is boot into my Windows partition or launch a Windows virtual machine. It’s not ideal, but it works.
