Reduce startup time of gunicorn workers

[sainak]

The booting of gunicorn workers puts a lot of load on the server on initial requests.
So we need to discuss a way to distribute or offload this initial processing.

possible solutions:

• use sartup scripts to load the littletable in memory
• do a staggered start of workers and load the little table on boot itself
• share the little table across the workers using redis or something similar
