Is it possible to avoid unecessary memory allocation when using weval(W"Func"(pars)).Even native Methematica Func will need memory and this cause trouble for millions times of calculation.

Unfortunately, I don't think this is generally possible. It might be possible in the case of large arrays of floats, depending on which protocol is used. What is your use case?
