Lenovo m72e on 11.2.0 zips thru a massive image of 10gb in 12 minutes.
On 11.2.3a the duration is 23 minutes.

We were thinking it was a driver issue with the Realtek r8169 Nic - saw other thread suggesting Intel chipset issue and/or an kernel issue supossedly poping up in the 11.2.2 and onwards.

Have installed the april image driver update - no change.

Other slightly older Lenovo models image just as fast as before - but since we are looking at 500+ deployments next week this slowdown is critical.
