Hi,
I have JServ 1.0b1 installed on a linux box running Apache, and JServ 1.0b3
installed on an NT machine where my servlets actually reside and execute.
Quite often when I do a POST to the webserver there is a great delay before
the webserver sends a response back. By great delay I mean 3-8 seconds.
Since these machines are both on the same LAN and have no other considerable
load, I term the delay as great.
Below I've attached a snippet of the logfile. As you can see from the
logfile, the servlet did not send the response headers until almost 3 full
seconds after the doPost function exited. This delay does not always occur,
and when it does, it does not always occur there. I have also seen a
similar delay between the 'Initializing servlet request' and 'Reading
Request Data' log entries.
Has anyone else experienced anything like this or have any ideas what might
be causing this? It is my goal to scale this application to something like
10,000 concurrent users... I may be forced to abandon servlets altogether if
I can't get this delay eliminated.
Thanks,
Rob
