100并发可以正常返回，200就会有这个错误，看请求都是正常的，但是压测结果无法返回
ERRO[0080] failed to handle the end-of-test summary error="GoError: failed to open connection, error: failed to verify client version: read tcp *****:22811->******:9669: i/o timeout \n\tat reflect.methodValueCall (native)\n\tat file:****/nebulagraph-bench/templates/k6_config.js.j2:12:27(59)\n"

graph 上有错误日志么？可以试一下 150 并发会不会有问题，然后看一下 graph 使用了多少的 cpu
