I have already reported this before but we are still in the same place.
The problem: When starting a new session in Logos 7 (Windows), the first attempt to use a field that produces a suggestion list takes a long time to populate.
The latest (out of many) instance: I typed h:yhwh in the Bible search box and had to wait over 30 seconds for the list to populate with suggestions. My laptop is otherwise performant. The same type of thing happens with other boxes that populate with suggestions (PG, BWS, Factbook, etc).
After the initial delay, subsequent searches are immediate. But since I shut down my computer every night, I have the same problem every day. There are times when I need information right now and I have to give up because of the delays.
As I said before, considering all the indexing that users have to endure, we should not have to have to wait like this all the time (it's even worse in the Android Bible app searches).
I am sure that some explanation can come up to explain to me how it must be so. But bottom-line is that whatever is the cause for this is really poor design and it does need to be fixed.
