I was a StumbleUpon user. Then I got fed up with they big toolbar. I switched to delicious, which was lighter, faster and more beautiful. Until Yahoo bought it. Then the export API broke all the time, delicious became slow and was ditched by Yahoo. I switched to Diigo, which is not bad, but does too much. And Diigo is sslllooooowww and their Firefox extension a bit buggy. And… oh… **their Firefox addon sends to Diigo every single URL you visit** (Don't believe me ? Use [Tamper Data](https://addons.mozilla.org/en-US/firefox/addon/tamper-data/) and open any page).
Enough is enough. Saving simple links should not be a complicated heavy thing. I ditched them all and wrote my own: Shaarli. It's simple, but it does the job and does it well. And my data is not hosted on a foreign server, but on my server.
First of all, ensure that both the [web server](Server-configuration) and [Shaarli](Shaarli-configuration) are correctly configured, and that your installation is [supported](Server-requirements).
It's not slow at all, is it? And don't forget the database contains more than 16000 links, and it's on a shared host, with 32000 visitors/day for my website alone. And it's still damn fast. Why?
The data file is only 3.7 Mb. It's read 99% of the time, and is probably already in the operation system disk cache. So generating a page involves no I/O at all most of the time.
