If you expect to serve complex pages with manyimages or other components that are fetched separately, or if anypages may take a long time to send, then it may be useful to increasethe number of server threads. For most uses, however, the connectionqueuing in the TCP/IP stack and the speed with which each page isgenerated, means that a single thread is usually adequate.</P></DIV><DIVCLASS="SECT2"><H2CLASS="SECT2"><ANAME="AEN15275"><TTCLASS="LITERAL">CYGNUM_HTTPD_THREAD_PRIORITY</TT></H2><P>The HTTP server threads can be run at any priority. The exact prioritydepends on the importance of the server relative to the rest of thesystem. The default is to put them in the middle of the priority rangeto provide reasonable response without impacting genuine high prioritythreads.</P></DIV><DIVCLASS="SECT2"><H2CLASS="SECT2"><ANAME="AEN15279"><TTCLASS="LITERAL">CYGNUM_HTTPD_THREAD_STACK_SIZE</TT></H2><P>This is the amount of stack to be allocated for each of the HTTPDthreads.
