I had a small Japanese oriented url shortening service. It got shut down because it used too much resources (CPU time and maybe memory) on a shared server. This was a couple of years back but I am interested in bringing back to life if I can afford to.
I am planning on using http://tighturl.com/project/ this time, and was wondering if the smallest VPS from say linode would be able to handle the work load. Most of the work is just mod_rewrites.
It is ok if the site becomes slow, but not unbearably so. If there is interest in the project then I could upgrade the VPS. But am I correct in assuming that even if the VPS gets swamped it won't get shut down because of affecting the performance of other users?
