 # allocbench - benchmark tool for POSIX memory allocators
 
 allocbench is a POSIX memory allocator benchmarking framework and tooling.
+It was used in Florian Fischer's [BA thesis](https://muhq.space/ba.html).
+
+What can allocbench do for you ?
+
+* Deterministically builds and patches allocators from git or source archives
+* Couples allocators with various included benchmarks as well as your custom ones
+* Supports you in analyzing your benchmark results by providing statistical and plot helper functions
+* Comes with support for two different malloc tracers to help you understand benchmark and allocator behavior
+* Contains numerous wildly used benchmarks in allocator research (espresso, cfrac, larson, ...)
+* It is extended easily with our own allocators and or custom benchmarks
