There is not enough information to answer this. I.E. what is the speed of the CPU? How about the RAM? What is the drive input/output [I/O] performance? 28,000 what? Time points? If so then 100 time points per hour seems reasonable for a drive with slow I/O.
Check the output file for the memory settings. If the solution is running "out-of-core", meaning that the fea matrices/vectors are stored on the drive and parts moved to/from the RAM for solving, then the solve could be very slow without considering the other drive I/O i.e. writing results to the result file.
