We have inserted 24 000 assets into 1 node on 1 server in 12 minutes.
At the same time we were inserting 8000 assets into the same chain on 2 other nodes.
This other 2 were inserting significantly slower, probbably becasue they were spending a lot of time on syncing.
Anyway when we finished inserting 24k assets into the first node and while other 2 were still inserting we ran "listassets" on the first one. This took about 3 times more time than it did to insert the 24k assets so naturaly the question is why is it taking so long? Are you aware of this and are you working on it?
