Dear all, Some strange phenomenon makes execution of PARI/GP up to twice slower when ran inside a Python process compared to its execution in GP. Though this is not systematic, in a fresh python environment timing are comparable with GP.
The slowdown has been first observed in the context of pari_jupyter [1] and then with cypari2 when sage.all is loaded [2]. There is a short code snippet in the description of [2] that you can try on your own sage version (must be ran with "sage -python" and not "sage"). Any idea on what could be the source of the slowdown or some profiling advices would be very welcome.
