Application response times are high with cometd calls

while executing performance test of salesforce application there are transactions with cometd calls. For such transactions, either the response time is high or I'm getting forbidden error "unknown client" in the response.

Is there anything which needs to be done from scripting perspective? P.S. - I am using Load runner for scripting.

Request

[{“id “:=”5”,” channel”=”/meta/connect”, “connection type”=”long polling”, “client id”= “####”}]

Response

"advice": { "interval": 0, "reconnect": "handshake" }, "channel": "/meta/connect", "id": "5", "error": "403::Unknown client", "successful": false, }

Please note: 1)sdfc-stream cookie is consistent throughout 2)Authorization < token> header is added in the request

The /meta/connect channel is a reserved channel used for the CometD heartbeat, and when using HTTP it performs "long-polling".

As such, it is natural that the request is held by the server for a longer time.

You must not use any /meta/* channel for load testing, but broadcast or service channel (see here for the channel definitions).

Not specific to SalesForce, but the CometD project has its own benchmark, see https://docs.cometd.org/current/reference/#_benchmarking. You should look at that as an example about how to perform a correct benchmark for CometD.
