Ask HN: do you have any low end boxes/VPS? If so, what do you do with them?

The more impressive the better. I wonder if there's someone out there who's hosting a 10,000 uniques/day site on a 128MB VPS. I have 3 VPS that i pay roughly £12 a year for. One is a personal VPN, one serves files for a small VB app i'm making and the last one just serves as a place to mess around in and test different configurations out. I also host a site for friends on my Raspberry Pi which is hosted at home (works great btw). I run nginx on everything, but my playground VPS is running Lighttpd as i want to test something new.

I get zero to 5 visitors (friends) to my sites at any one day. Due to this, i don't know how well my VPS or my Pi would handle a larger amount of visitors. Are there any recommended tools to test this?
