 \begin{abstract}
-This is the text of the abstract.
+By introducing loop peeling into the optimization step of a tracing
+jit, the effect of optimizations already in place will be increased
+greatly. Not only will they become able to move loop invariant code
+out of loop. They will also become able to reuse results from the
+previous iteration. Also, the implementation of excising optimizations
+can be left almost intact as they will not have to interact much with
+the loop peeling.
+
+Several benchmarks executed on the PyPy python JIT show over 2
+times increase in speed when loop peeling was introduced. This makes
+some of them almost match optimized C performance and become over XXX
+times faster than cpython.
