[pLog-svn] about plog perfomance

[nick nizhenyuan]

I tried the plog1.0 code with DB cache, the perfomance improved very much.

>From my site, thousands of people get to know about plog, including
www.newradio.cn.

So some people discussed with me about the Plog, the conclusion is
that plog has a very great MVC structure which make it strong and
extentable.

But we also wonder that, will this kind of structure make it slower?  

How do you think? Anyone tried to compare/analyse the perfomance of
plog which adopt a fully OOP and MVC structure?
