This is a plot of the amount of documents created in a bulk update at the same time against the average amount of documents created per second it yields.

Some people are afraid that Google App Engine won’t be a really big success because it’s a lock-in. Give it a month and no doubt there will be a project which allows you to run AppEngine applications on your own servers, which (in my opinion) is even more interesting than AppEngine itself.
I’ve written a small benchmark for couchdb to test it’s document creation performance. A script creates documents in total using bulk update to create at the same time with concurrent threads. The following graph show the time it takes to create an amount of documents against that amount of document for different values of with .
As you can see, a higher value of causes the graph to shift to the right which means more for the same time. Bulk update really does make a difference. Or non-bulk-update really sucks. Also adding threads does help a bit, but not as much as expected.
There are some more interesting graphs to plot ( against ). More graphs tomorrow.
(For those interested, the raw data from which these graphs were plotted.)
