Wave server becomes slow over time

[n-srinidhi]

Hi! I have a wave dashboard app in production. It is deployed on a Windows server with around 40GM of RAM space.
My Wave dashboard makes multiple API calls to two backend engines running on the same server, The app accepts multiple user accesses and renders data individually to respective browser client based on user-id maintained internally in a q.client variable.

The issue is after around 8-10 hours of being up and serving multiple requests at once, The wave server slows down. Responses that took 10-20 secs on startup now take around 4 mins. I am continuosly updating my front end every 10 secs using a futures background process. What can i do to improve the performance and avoid the server from slowing down? Is it a server load issue?
I'd appreciate any pointers for this!
