calculation time

[Takuya Sekikawa]

Dear PETSc/SLEPc users,

I have made eigenproblem solver program with SLEPc.
Currently it works well, but it takes very long time to solve big
problem.

with 10000x10000 random matrix, it takes about 34 hours to solve.
(solver = KrylovSchur, on 64bit Linux platform, 16G memory, 1 machine)

Is this ordinally time to solve problem like these size?
or Is there any good way to shorten calculation time?

Thanks
Takuya
