I can attest to that.

Some months prior to 2013-08-23 (release date of 1.0) I had a custom column in one of my libraries that was built from a union of four other columns, when that library went past about 4K books calibre became very slow, when I removed the custom column normal service was resumed.

Sometime in September I tried reinstating the custom column, now it had no discernible effect on performance. I now have about 8K books in that library and performance remains very good.
