-----------------------
Description:
When using the transform in the plugins, the query results from traffic_line is

proxy.node.http.origin_server_total_response_bytes will becomes very slow
growth when using any transform in the plugins.
test :
origin server:127.0.0.1:80(nginx);
ats(4.2.0) never-cache;
qps:25
request file: 25M
