Answer 1

慢可能是因为这些域外的js引用
<script src="http://webpresence.qq.com/getonline?Type=1&666267:111055:655603:"> </script> 
因为访问的是域外的服务器，跟网速、对方的服务器访问速度等有关系

Answer 2

一个简单的，并且可以读取数据库的QQ是否在线判断，并且在线和不在线的图片可以自定义：
<table width="85%"  border="0" align="center" cellpadding="0" cellspacing="0">
           <% 
while not rs.eof 
qq=rs("QQ")
%>
<tr><td height=20 > <script> 
var online= new Array(); 
</script> 
<script src="http://webpresence.qq.com/getonline?Type=1&<%=qq%>:"></script> 
<script type="text/javascript">
qq="<%=qq%>"
qtname="<%=rs("qtname")%>"
qqimg="<%=rs("qqimg")%>"
offqqimg="<%=rs("offqqimg")%>"
bz="<%=rs("bz")%>"
zwmc="<%=rs("zwmc")%>"
swname="<%=rs("swname")%>"
MSN="<%=rs("MSN")%>"if (online[0]==0) 
document.write("<td height=20 ><img src="+offqqimg+" border=0 align=middle></td><td height=20 ><a class='qqb' target=blank href='http://wpa.qq.com/msgrd?V=1&Uin="+qq+"&Site=在线咨询&Menu=no' title='不在线，请留言 &#10 &#10 商务名称："+swname+" &#10 &#10 职务名称："+zwmc+" &#10 &#10 MSN："+MSN+"  &#10 &#10 简介："+bz+"'>"+qtname+"</a>"); 
else 
document.write("<td height=20 ><img src="+qqimg+" border=0 align=middle></td><td height=20 ><a class='qqa' target=blank href='http://wpa.qq.com/msgrd?V=1&Uin="+qq+"&Site=在线咨询&Menu=no' title='在线即时交谈 &#10 &#10 商务名称："+swname+" &#10 &#10 职务名称："+zwmc+" &#10 &#10 MSN："+MSN+"  &#10 &#10 简介："+bz+"'>"+qtname+"</a>");
