[Grok-dev] Exporting Apps

[Sebastian Ware]

Yes. The snag being that one needs multiple Grok instances running and  
with many instances that till eventually cause swapping. So it would  
probably benefit from running on a solid state disk.

I use Nginx in front of several instances of Grok and it is very  
efficient.

Mvh Sebastian
