RE: Tomcat 5.5.17 has max 40 KB / sec

2006-09-25 Thread Steffen Heil 
Hi

I know, reasking the same question if there was no answer, is no good style.
However I had problems using apache-lists earlier and I don't know wether my
mail made it to the list.
So could anyone please respond, that the mail itself made it?
(Solutions to my problem are welcome as well :D )

Sorry and regard,
  Steffen

 Hi
 
 I use tomcat 5.5.17 and want to upload files. As this was 
 *very* slow in some cases, I wrote a benchmark servlet. Code is below.
 I get the following statistics:
 
 1. Running server on debian linux it accepts about 8.5 MB / 
 sec. (Could slowed down by VM overhead.) 2. Running server on 
 windows xp it accepts about 3.5 MB / sec when the client is 
 connected over an rinetd redirection.
 3. Running server on windows xp it accepts ONLY 40 KB / sec 
 when the clinet is connected directly.
 
 This problem applies to Internet Explorer 6.0 as client only.
 It does not occur so with Firebird (but still only about 2.4 
 MB / sec).
 
 Using wireshark I found that the Internet Explorer is sending 
 only 8 KB
 (exactly) followed by an tcp PSH, which is not answered by 
 the windows xp machine running tomcat for 0.2 sec. That gives 
 me exactly the 40 KB/sec.
 
 I would say, my xp tcp stack is damaged, but it works with 
 the same server, when redirected through an external rinetd.
 
 What can I do ?
 Where can I start debugging ?
 Anyone having similar problems ?
 
 If possible, please also reply to me directly (CC).
 
 Regards,
Steffen
