Re: PSAMP open issue 18: export rate limit?

[Tanja Zseby <zseby@fokus.fraunhofer.de>]

Hi Benoit,

I think originally this was about controlling the report rate. 
Furthermore I think it could be difficult to control the number of bytes 
(although it may be a useful feature) by the exporting process. So for 
now I would only target the report export rate.

Regards
Tanja
