Compare B2R2's disassembler against several other libraries

Comparing B2R2's disassembler with Iced, SharpDisasm and Capstone.NET

In this repository, we compare the speed of B2R2's disassembly with 3 other well-known disassembly libraries. For the comparison, we use three different raw binary blobs that we gathered from default linux distros as follows.

Binary Blobs Used

1. blob_x86
2. blob_x86_64
3. libc_x86

Comparison Targets

We compare B2R2 (v0.5.0) against three .NET-based tools. For Capstone, we used both the Python version and .NET version.

• Iced
• SharpDisasm
• Capstone.NET
• Capstone(python)

Commands to Run Each Tool

<bit-length> is either 32 or 64, and <target file path> is the path to one of the blobs.

B2R2

dotnet run -c release --project b2r2_test/b2r2_test/b2r2_test.csproj <bit-length> <target file path>

Iced

dotnet run -c release --project iced_test/iced_test/iced_test.csproj <bit-length> <target file path>

SharpDisasm

dotnet run -c release --project sharpdisasm_test/sharpdisasm_test/sharpdisasm_test.csproj <bit-length> <target file path>

Capstone.NET

dotnet run -c release --project Capstone.NET_test/Capstone.NET_test/Capstone.NET_test.csproj <bit-length> <target file path>

Capstone(python)

python capstone_test_python.py <bit-length> <target file path>

Results

Below is the result showing how many seconds it took to disassemble each binary blob (lower is better). Each number is the average of 10 repeated runs. B2R2 took the second place, but please note that B2R2 is not merely a disassembly engine: it can lift a binary into a well-formed IR, and it can recover CFG from it, and many more.
