java - Tomcat request.getParameter("_xmldata") takes 25second for 30MB data -

i have clients need post 30mb of xml data. info in binary form , heavily encrypted. client nail servlet running on tomcat, info via servlet request.getparameter("_xmldata");

the problem is, takes around 25seconds move 30mb info string variable. in head, there 2 questions:

1) why case?

2) there anyway can improve this? (apart getting user send via ftp / ssh)

server environment:-

cpu: quad core xeon 5540 server memory: 4gb tomcat heap: 2gb harddisk : 500gb

i'm going wager guess getparameter method still waiting on necessary info within request received. confirm monitoring server wireshark.

all required http request headers have been received, plenty server start processing request. 1 time phone call getparameter, still waiting entire "field" received. check bandwidth between client , server. highly uncertainty it's cpu issue (nothing you'd need quad core for).

you confirm placing little test text fields both before , after _xmldata field in request. read these fields around _xmldata. i'm guessing attempting read lastly encounter same delay you've been observing.

(i'd cautious how you're receiving binary info through request parameter - , furthermore, moving string variable. i'm hoping it's encoded base64 encoding...)

java tomcat getparameter

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
