python - Is concurrency possible in tornado? -

-

i understand tornado single threaded , non-blocking server, hence requests handled sequentially (except when using event driven approach io operation).

is there way process multiple requests parallel in tornado normal(non-io) execution. can't fork multiple process since need common memory space across requests.

if not possible please suggest me other python servers can handle parallel request , supports wsgi.

if going dealing multiple simultaneous requests compute-bound, , want in python, need multi-process server, not multi-threaded. cpython has global interpreter lock (gil) prevents more 1 thread executing python bytecode @ same time.

most web applications little computation, , instead waiting i/o, either database, or disk, or services on other servers. sure need handle compute-bound requests before discarding tornado.

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
