The size is to be expected but the import time seems overly long. If you don't use SSDs then this is a likely cause as a good IO performance is crucial for the import.

My question is: It is not a good idea to run queries while the import is still running. There are a lot of indexes still missing which are important for search. So you end up with a lot of sequential table scan which make not only your queries slow but also have a negative impact on the import in progress. Once the import is finished you will see much faster responses.
