Import of Entities is taking very long time..

[Minal Pathi]

Hello

I am facing difficulties  in importing enttities from an exported zip file. It 
is taking more than an hour to import 500 entities. The zip file is of 17.6 MB 
with around 4000 entities.

These are the options I provided in the import-options.json file: {
    "options": {
        "numWorkers": 6,
        "batchSize": 300,
        "format": "zipDirect",
        "migration": "true"
    }
}
numWorkers=6 as we have 2 shards in Solr

and the curl request is as follows:
curl -g -X POST -u admin:admin -H "Content-Type: multipart/form-data" -H 
"Cache-Control: no-cache" -F request=import-options.json -F 
data=@export_new.zip "http://localhost:21000/api/atlas/admin/import";

Can anyone please point out to me any enhacements which can be done for faster 
entity imports?

Thanks and Regards
