Description
Hello,
AVL tree integration in DataStructures.jl was discussed in #503 but it seems that this implementation is slow (especially for search operation).
See benchmark https://github.com/femtotrader/AVLTreeBenchmarks.jl/ for a comparison with @krynju implementation https://github.com/krynju/AVLTrees.jl and discussion https://github.com/p-casgrain/LimitOrderBook.jl/issues/7 (LimitOrderBook.jl from @p-casgrain )
Best regards,
Femto

Research direction
Start with the AVLTreeBenchmarks.jl benchmark linked in the issue and inspect the DataStructures.jl AVL tree implementation it exercises. Compare search results with the referenced AVLTrees.jl and LimitOrderBook.jl discussions; done means the AVL search performance is measurably improved and the benchmark demonstrates the change.
