wanfa deng created PROTON-2229: ---------------------------------- Summary: pn_data_t initialization lead to low performance Key: PROTON-2229 URL: https://issues.apache.org/jira/browse/PROTON-2229 Project: Qpid Proton Issue Type: Bug Components: proton-c Affects Versions: proton-c-0.30.0 Environment: x86_64 GNU/Linux Reporter: wanfa deng
Recently I update qpid-proton from 0.28.0 to 0.30.0 version, and find massive produce performance fallen by 80%。 Finally,I find this is caused by pn_data_t initialization。 In 0.28.0 version, it's like data->buf = pn_buffer(64); and in In 0.30.0 version, it's like data->buf = NULL; And when data->buf is initialized by NULL, in the following call flow, pn_data_put_binary->pni_data_intern_node->pn_buffer_memory->pn_buffer_defrag->pn_buffer_rotate, buf->start is more likely not equal to 0, this is leading to buffer rotate, and make the performance lower. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
