Day 46 - Performance Tests

I know it's Saturday, but a lot of data migrations work is done during the weekends. Specially during the last weeks before the end of the project.

But this Saturday, we were focused on performance tests. We had the AS/400 entirely for us for about 3 hours.
We executed performance tests for the transformation rules engine and for the GIS data loader.

As excepted, the performance increased both with a single process and with multiple processes. for both systems.
In the transformation engine we've executed up to 6 parallel migrations, but the maximum gain was below that, the 4th or 5th, depending on the transformation features, more I/O bound or more CPU bound.

There was not time to perform one interesting test though, running the transformation engine at the same time as the GIS data loader.

Nevertheless, the outcome was what we expected: to have a dedicated Intel machine running Linux for the exclusive usage of the Data Fusion. This will allow GIS data loader to have more resources, since we're not competing.

Here's some nice charts from the tests performed.
