I perpare a loadscript to load 1.600.000 records through a webservice in a backend system.
The performace to load this kind of records is very slow.
When 1 increase the threads then i got double records.
So 2 threads result in 2 double records, 3 threads --> 3 same records.
How can i increase the speed without getting double records?
Please see this article which explains what factors are affecting performance: System Requirements for Large-Scale Load Tests. To optimize the memory usage, please refer to this article: Optimizing Memory Usage.
