Jérôme Duriez proposed the following answer:
Hi,

The only method I see, outside buying a new computer or doing parallel
computations, is to identify the parameters that won't affect your
results and abandon the idea using physical values (and use "convenient"
values instead).

A first (probably non-consensual on this mailing list) example is to play with "density scaling" in case your problem is quasi-static: increasing particles density (which has no influence on the results in this case) in order to have a higher critical time step, see the DEM literature.
For displacement controlled loadings, the maximum admissible loading rate may become smaller leading to some trade-off, but, as far as I'm concerned, I could still obtain some gain in terms of computation time.

You may also play with "timing" module of YADE (see the doc) to check
that you do not have any unnecessary bottleneck in non-essential engines
(probably not)..
