Continuous batching load test limited at 75 VU with 1x3090

[Kev1ntan]

Hi, i am doing a load test on vllm server. below is the way to reproduce:

instance: 1xRTX 3090

load test tool: k6

server command:
python -m vllm.entrypoints.api_server --model mistralai/Mistral-7B-v0.1 --disable-log-requests --port 9009 --max-num-seqs 500

then run k6 with 100 VU:

export const options = {
  vus: 100, // simulate 100 virtual users
  duration: '60s', // running the test for 60 seconds
};

i tried to adjust the --max-num-seqs and --max-num-batched-tokens but still cant pass 100 VU. is there any best config for the server?

any help is appreciate, thank you.
