I'd be shocked if you really couldn't tell any major performance increase from upgrading your netbook from 1GB to 2GB ram. What OS are you running?
I recently bought a netbook, as it is easier to take on the bike than my laptop, and the upgrade to 2GB ram was like night and day. It was practically unusable with 1GB of ram (running Win7).
To me this would indicate you have other issues you are not aware of that are still taking up all of your ram despite the upgrade (e.g. a plethora of startup programs running in the background, malware/spyware, fragmented HDD slowing down read/write times, a huge collection of temporary files that need to be removed.)
