scalability of JasperServer

[nirum]

Hi All

   I have a question for the user community of JasperSoft and  impementation specialists/professional services of JasperSoft.

Have you handled installations where thousands ( literally ~ 500000 users) have been deployed on a JasperServer. If so, how did you do the administration part for these thousands of users on a single Jasperserver. If each of the user needed their personal reports and adminstrative space, how did you set these up painlessly.

Do you have any solutions/sugggestions for such a large installation.  How scalable is JasperSoft in this respect and how did it handle hits to the server by atleast 10% of this population at a time.

Thanks for your insights and help in this matter,

Niru
