Hi Johan,

Yup I have DHIS2 up and running on two boxes we're comparing performance on: a 1.2GHz, 512MB RAM system, and a dual core Intel Atom 1.6GHz, 2GB RAM system.

Your suggestion to use the data mart export made for a very helpful test...thanks!� We were actually surprised to see a relatively small performance difference between the two.� My initial tests use:

export all data elements, all indicators, for the entire Sierra Leone organizational unit for the months of June 2008, July 2008, and August 2008. (I plan to scale up and use more dates later...but it's difficult since I can't automate the timing I have to use a stopwatch and keep an eye on the window to make sure I stop the clock when it finishes.)

This takes approximately 6m20s on the single core system, and 5m on the dual core.� Does this sound reasonable?� We had perhaps expected a greater bump in performance from the more powerful hardware.

Thanks again for your help,

Andris

Thanks Andris,
I've forwarded all the info to the right people.

btw, did you manage to get latest DHIS2 up and running on your machines,
and with the latest Sierra Leone database?

Johan
