No surprises there.
The algorithm for sorting/arranging the labels is being called
frequently, isn't particularly efficient and is probably being called at
times when it doesn't need to be.
Please raise as a bug in Bugzilla. P3 I guess.
There are probably some changes that can be done quickly that will make
1,000 labels tolerable. I hope to have a look at it before the next
release-freeze. [I'm going to use 'release-freeze' from now on rather
than the term 'double-freeze' since it's clearer.]
