TO be honest you are not going to find a very fast 10" laptop (netbook) as they are designed for low power and portability, not speed. and as such they are all pretty much on a par when it comes to speed and specs (all being based on the Atom processor, a low power processor)
The slight exception is there some dual core atom based netbooks on the market (your one is only a single core) which will have a little more go in them, I've not used one to offer comparison but I'd still not expect them to be a power house!
If you need the extra power then you've got to start looking at 12-13inch laptops with the full spec processors in them rather than 10inch with the low power processors but, as always, you get what you pay for and if you want portability and power you are going to have to pay a lot more than your EEE PC cost you!
As a side... I have an EEE PC myself and find it perfectly usable for most things (certainly all the things I'd expect this class of machine to be used for) without any serious speed issues, but it does have to be kept as a very clean, streamlined install, if you start loading a netbook up with all the sort of rubbish and unnecessary background tasks that most systems end up with on them then performance will seriously suffer.
