Is there something wrong with this sites statistics?
This is a question I asked yesterday, it states it has been viewed 3 times, yet there are 6 votes. If you see different maybe there is something wrong with my computers cache.
This has come up a few times on Meta Stack Overflow. The explanation seems to be (1) the views counter is approximated, but votes are not; (2) there's caching involved so updating the views counter isn't done instantly; and (3) the views counter depends on unique IP addresses so multiple accounts sharing an IP address will only show up as a single view.
So I doubt it's a bug.
This is primarily due to database caching where some of the information displayed (such as the number of views on a post) is stored locally rather than checking the database each time for the latest up-to-date number. It's a performance enhancement that generally works well across all sites, but this side effect is much more pronounced when a site has less traffic. It will hardly be noticed once the site starts humming along.
