VecLoad very time consuming

I have implemented a code for resolve with PETSc the linear system inside a
Newton method writed in matlab, I am using the socket communication between
Matlab and Petsc, but i get that about the 95% of the time is spent in the
VecLoad() function. Is this behaviour normal? for the overhead time in the
communication and writing and reading to/from binaries?

I am attaching the log_summary

Thank you
