Writing the result of correlation function to XML file takes a lot of time.

I'm calculating the one particle reduced density matrix, so it's the cdag_up:c_up, and cdag_down:c_down.

Hi, everyone I'm using sparsediag to get the ground state of Hubbard model, e.g. L=12, with the particle number constraint Nup_total=6, Ndown_total=6. Using the command line. If I calculate the correlation function , it takes 900 sec, if not it takes 100 sec, does anyone know how to speed up this calculation?

Btw if I use python to run the result, I can't see the result from the task.out.xml file, how to look up the result
