That's actually slower-than-Atom class hardware you're running on there, with full disk encryption on what's a very CPU and IO-heavy workload. From the benchmarks I remember, your CPU is literally slower than the first generation of single-core netbooks - the ones reviewers recommended against using full disk encryption on because they just didn't have enough CPU power to manage it. It's not surprising that Bitcoin isn't usable on that setup.
