Collecting type info is slow

With :set +c option in GHCi, I'm waiting for 10-15 seconds for

Collecting type info for 34 module(s) ...

after both first load and subsequent reloads, even if only top-level module was modified.

And GHCi uses about 1.5-2x more memory than it uses without :set +c.

My app has about 30k lines of code.

Is it expected behavior and some performance improvements are planned or it's a bug?
