Publishing faster with static collections

The app was publishing quite fast (within a minute) when there were no static collections. Now there’s one active static collection being user with about 230 items using 0.1/25MB quota. The publishing time has shot up to about 5 minutes.

I’m trying to figure out if this normal behaviour. Also if one would expect the publishing time to grow linearly with the static collection size.

WeWeb prerenders each page (I think), so it naturally takes longer.
