OutputStream and servlet

[bigbinc]

Does anybody know how servlet for example tomcat writes data to the
socket outputstream. For example,

based on the code below and getWriter, should I call 'flush' within my
code for example if I have a lot of data being outputted or will
out.flush() doing anything because servlet engines process output till
the end. Lets say I have a string that is 1MB, should I parse the
string up and do a out.flush() or just
do:
out.print(BIG_STRING)
out.flush();

jasper,tomcat performs out.write... for each line of text.

It looks like the buffer size is 8k.

_jspx_out = out;

out.write("// aimsBuffer.js\r\n/*\r\n* JavaScript template file
