Here is a suite of performance tests for the dolfin assembler: http://www.csc.kth.se/~dag/dolfin/dolfin_assembler_bench.tar.gz It does seven tests. Assembly and reassembly of the following (bilinear) forms: Elasticity (3d), Incompressible NS Momentum (3d), Laplace on linear (2d), Laplace on quadratic (2d), Laplace on cubic (2d), Stokes TH (2d), Stokes stabilized (2d). This seems to me to be a blend of different types of forms. The design of these tests is as modular as possible, so one can easily add more tests. The top-level SConstruct builds the whole thing. Run with run_tests.py The output as produced by by workstation (2.4GHz Core2Duo, 2gb ddr2, 32bit os) using the uBlas backend: http://www.csc.kth.se/~dag/dolfin/results_uBlas_opt There clearly is a spread in assembler performance for different forms. I suspect that you want to tweak the assembly_tester function to make it backend-invariant.
