Troubleshooting slow response from Cortex XSOAR which
maybe caused by the buffer size in the WebSocket communication protocol.
A WebSocket communications protocol is used in Cortex
XSOAR for bi-directional data transfer between the client browser
and the server. WebSocket communication enables data to auto update
without refreshing the browser.
If a user experiences a slow response from the Cortex XSOAR server
and does not receive data updates on certain pages and actions,
the WebSocket may be disconnecting.
If you see errors in the logs like the message
below, increase the buffer size in the server configuration.
