[pve-devel] slow migration speed / again memory usage

[Stefan Priebe - Profihost AG]

Hi,

i'm still trying to understand the memory usage and the migration speed.

I've a VM which does nothing else than running SSH and a cron job every 
minut to write a small json file.

When the VM is freshly started Proxmox shows 300MB Memory usage and 
migration speed is around 400MB/s and takes a few seoconds.

After time the memory usage increases in Proxmox up to 3.7GB but in VM 
it stays incl. cache and buffers around 350MB.

The migration speed is then around 25MB/s.

How can this be? Is this expected?

Stefan
