improving time response in Event Data Import?

Dear dev community,

From PSI, sometimes we need to import into DHIS2 large xml files of events (using the Event Data Import) following the schema described in the manual. This functionality really takes a long time in DHIS2.

Just to give you an example: 6.000 events and a total of 45.000 datavalues could take around 7 hours or more to be succesfully imported. Maybe we would need to import a larger volume than that. Could it be possible to decrease the time used to perform the Event Data Import? We are using 2.13 and 2.14 .

Many thanks
