Physical to Azure Conversion Slowness

[shirasu]

Hello! I'm currently converting a VM, It took 24 hours for a 240GB drive to transfer to the storage. I now have a 2TB Drive that hasn't even moved the needle.

When I check network performance in task manager it shows that Starwind V2V Converter is only using 21.9 Mbps. We're on a 1G symmetrical network which all speed tests are confirming. Upload tests to azure also show great speeds. Any suggestions on how to rectify this? At this rate its going to take a week to finish.

Welcome to StarWind Forum.
The slowness can be coming from the underlying storage performance and the fact that V2V is single-threaded.
Check the underlying storage performance under large blocks; if it is good, sadly, that's more of an issue for the design of an app (we are looking towards optimizing it).

Hey Yaroslav, I'm doing P2V from Physical to Azure, Storage doesnt seem to be getting hit hard at all.

I will log the internal request to see if we can improve the performance.
This will be a long process.
