Definitely SQLite will be a bottle neck in this system – not great for writing to – both Pg or MySQL would be an almost certainly better solution for repeated writing to.
You could get some simple gains by splitting the database up so that there is a database per site rather than a database for all 10 sites – unless there is data to be shared between them – as you would have less database lock contention on the individual databases. SQLlite is not designed to be used in a situation where there are lots of write locks. And does not scale very well as the database gets larger… Also, just trying to get round what each visitor triggers in the CGI – and why it is a lot of work for the db – this is where you would need to make things easier for it & yourself, is the information you show useful to the user or could this just be processed some other way!

The clients are mostly casual browsers, but every visitor triggers the CGI so that's a lot of work for the db. Regarding the db it's currently an SQLite instance but I'm running about 10+ virtual sites off the same db and needing writes so that alone may be part of the problem. Also, I do have a good Pg db running I've intended to use but just haven't gotten a "round tuit" yet. But, could a web socket setup help do you think?
