Download fast but upload very slow on server
I'm facing issues with upload speed. My server are download very fast (fully speed 1Gbps) but upload speed just 3-7Mbps to same location of DC. DC checked on my server and tell issues from configure network but i was checked the configure network is fine. So, really i don't know the issues come from configure network or from DC. My server are running CentOS 7.5 with Virtualizor KVM. Anyone have facing this issues? And what solution for this? Thank you!
