If the results for the case with the time dependent boundary condition
look reasonable, then I think you will have to accept that pdepe needs
3-4 hours to solve the problem.
I don't see any way to optimize something here because the interface
of pdepe is rather stringent.
If you are interested in other software to solve 1d parabolic-elliptic
pdes, I can provide some links.
E.g. if you have access to the NAG Toolbox, you could try d03pc or
d03pd.
Take a look at
