Re-indexing is running around 10 times slower and when using JSD portal we get error massage that it can not send request, but the request is created any way

I did not get the error after finishing the indexing.

That should not be a problem most of the time - a background index is something you should be running infrequently and at a low-usage time.

What version did you upgrade from, and what other changes were made?  Did you change disks, server, database, location of the system or anything else?

My problem is not only the time, my problem that customers can not use portal while running  "Background re-index" which mean downtime for the service.
