I've run Ubuntu (9.04-11.04) on an Acer Aspire One netbook, but recently I've gotten a SR1620NX Compaq desktop tower. I installed Xubuntu on it and have noticed that most programs (but significantly Chrome) are extremely slow. It took 3 minutes to load Google Chrome and it usually takes about 1 minute to open a new tab.
Should I expect it to be this slow, or is there an issue with the RAM/Hard drive?
I installed htop [sudo apt-get install htop] and it says that (with only Chrome running) I was using 208 of 432 RAM. Is that normal? I'm not sure what to expect, since I've never bothered to check the RAM usage while running Chrome on my Acer.

Any help would be appreciated.
