Toumo brought up his old server, running F29, and I am doing a benchmark of 
testrun - time run our current KVM test suite using kvmrunner.

Here are the first results.
80 Minutes for a testrun. This is impressive to me.
Number of tests from master ~748.

|KVM_WORKERS/KVM_PREFIX| run time |
| 12/28 | 79 Minutes |
| 8/24 |  101 |
| 8/28 | 118  |

I suspect there is still room tune more.  We will see.

So the 7 year old Enterprise Xeon perform better than a new (6 months old)
basic servers in the same price range.

Specs of the server:
CPU: 2 x E5-2650L
RAM : 256GB = 16 * 16GB
HD :  8*2TB HGST enterprise sata disks
Motherboard : X9DRi-F

Similar systems go for about €1000 - 15000 (refurbished used servers)

However, Tuomo notes it is noisy when I run tests:)

New ONE: about €1200 
CPU: E3-1240v6 - https://ark.intel.com/products/97469
Ram : 64GB = 4 * 16 GB = 64 ECC ram
SSD : 2 * 500 GB Samsung EVO 960 SSD raid1
Motherboard : Supermicor X11SSL-F

I hope this motivates people to collect old Xeon servrs they are great 
machines for testrun:)

PS kernel compiling, 5.0.4, with F29 .config file takes 9 vs 20 minutes.
I suspect if I upgrade to SSD(from spinning disk) kernel compiling would be 
a bit more faster on the E5 server.
