I realised today that I’ve not written up a progress post for foswiki on MongoDB for a bit – and so did a few benchmarks again.
The benchmarks given (at http://foswiki.org/Development/MongoDBPlugin ) are for a structured query on a DataForm based web containing 25,000 topics, and are run on a desktop system running a 1.8GHz core2duo with 2G RAM.
When the foswiki on MongoDB project started, this query would take 5.4 seconds to provide the html to the client (pure CGI), now it takes 0.7seconds (with mod_fcgid).
That’s a speed-up of over 7 times.
Many other large web queries, like a WebIndex on a large web couldn’t even complete before, and now run in a usable fashion.
This milestone we’re separating out each web into its own database, and I’ll be adding in the topic revision information to the database too – that way it won’t matter if you have 10,000 webs, or 1,000,000 – the speed should be essentially constant (so long as you have the server resources to match your loads).
If noSQL isn’t suitable, and you would like to see a similar back-end developed using an SQL engine – contact me – WikiRing and fosiki are looking for interested companies with foswiki (and TWiki) scaling issues – without real life testing, examples and stakeholders, its extremely difficult find the many corner cases that our complex engine can allow.
