thor doesn't seem to make more than 105 parallel connections, even with -C 10000

I'm trying to test my server with the command thor --masked --amount 10000 -C 10000 ws://localhost:8080/hello/. The report is the following:

Received errors:

7x                   read ECONNRESET

It says it did (almost) 10k connections. But the server indicates that they were not made all in parallel; instead, at most 105 connections were opened at the same time.

Is there a way to force thor to make a specific number of parallel connections? Because the main reason I need it is to test how many connections my server can keep at the same time.

(Also, FYI — I'm using Jetty for the Websocket server implementation).

If anyone knows the answer to this I would also be really interested.

yeah, same happening with me. Around 80 connections opened in parallel. Either its in short batches.

New updates at this issue? I am using ratchet, connections reach 400-500 then start to disconnect.
