cpu & network usage is too high when connected realm-js client on the node-js server #386

Goals

I have been using realm-object-server with Android & iOS clients for about 11 months. Recently, I connected to the ROS using realm-js client on node-js server. Then, CPU and network usage of ROS is increasing too much.

Normally, if android & iOS client is connected, the CPU usage does not exceed 10%. However, when the realm-js client is connected for testing, the CPU usage increases to 100%.

Below is an old stackoverflow issue. https://stackoverflow.com/questions/50077066/cpu-network-usage-is-too-high-when-connected-realm-js-client-on-the-node-js-se

And I got a 100% case about this issue.

  1. Set the accessTokenTtl to 36 minutes or longer with server.start on the realm object server. (index.js file)
  2. Then realm js client re-connect to the ROS.

Expected Results

CPU usage should be normal.

Actual Results

CPU usage is over 100%.

Steps to Reproduce

Code Sample

accessTokenTtl: (1000 * 60 * 60)

Can I get support from the Realm team?

@bigparksh is this still an issue for you with the latest version of ROS?
