<BR><FONT SIZE=2 FACE="Arial"> The real issue which I want to highlight is not spammers but the</FONT>
<BR><FONT SIZE=2 FACE="Arial">Scalability of Jabber . The tests which I performed on Jabber clearly showed</FONT>
<BR><FONT SIZE=2 FACE="Arial">that it slows down which is definitely not acceptable in real-life</FONT>
<BR><FONT SIZE=2 FACE="Arial">situations . Jabber has to be more scalable than it is now . Any Thoughts</FONT>
