I changed my witness server for several days and I noticed it is taking a long time to remake a blockchain synchronization.

As you can see in the image below, 8 hours have passed and it's not full synched.

This is very strange becuse this my new server has more performance then the old one.

what I think is: even the cpu are more then the old server (12 cores), have the worst characteristics.

WHY CPU AND NOT RAM?

At the first sync, even if you had downloaded the file before, steemd process use only ONE CORE and not so much RAM.

I verified it into 2 different servers:

• Server one with 8 CPU
• Server two with 12 CPU

SERVER 1

SERVER 2

So i can say the problem for the first Sync is the CPU.

My old server takes around 3 hours and my new one take around 8 hours.

what I thought was:

Do I really have to wait all this time?

And i studied the possibility to make the CPU AFFINITY into Ubuntu whit the program called TASKSET.
It permit you to choose the core to use for a specific application.

SO I TRIED TO DO IT WITH THE SYNTAX:

taskset -c 0,7 ./steemd --replay-blockchain
This was done on my old server with 8 CPU

I HAVE TO SAY: The result was negative

The same result without starting the taskset.....

So i wrote into steemit.chat to ask if steemd is a multicore app or if it it a single core application and i received the @someguy123 response.

AT THE END I HAVE TO SAY: THERE IS NO POSSIBILITY TO SYNC WITH MULTIPLE CORE IN ORDER TO GO FASTER

I hope in the next future this will be fixed because It's really annoying to wait so much time to sync.

IF YOU HAVE MORE INFO ABOUT IT PLEASE LET ME KNOW.
