I have tried some standard benchmarks and my other python programs, and
cProfile makes things slower.
Hence, Aislinn is the only program where I can reproduce the weird behavior.

That's insane. Profiling slows down the application. Always.
Are you able to reproduce this on other scripts as well?

Hi
I have observed that Pypy is faster when cProfile is enabled than
its normal execution.
I would like to ask if it is a normal behavior or a kind of anomaly?
E.g. one of my benchmarks:
Pypy: ~24.5s
Pypy + cProfile: ~19s
CPython: ~22s
Tested with 2.5.1+dfsg-1~ppa1+ubuntu14.04, but I have observed a
similar behavior with older versions of Pypy shipped with Ubuntu
14.10 and 15.04. My application is a pure python application that
communicates through sockets. (It is a state-space analytical tool
that communicates with a modified Valgrind process through TCP/IP
connection).
A replication of results:
Build: https://github.com/spirali/aislinn (Installation
instructions:

cd aislinn/tests/complex/workers
../../../bin/mpicc workers.c # build an analyzed program
time pypy ../../../src/aislinn/aislinn.py -p4 ./a.out 10 90
time pypy -m cProfile ../../../src/aislinn/aislinn.py -p4 ./a.out
10 90
time python ../../../src/aislinn/aislinn.py -p4 ./a.out 10 90
