Uhmm, that's not actually always true. I have done<BR>
some benchmarks in the past and this is what I think<BR>
I have noticed:<BR>
<BR>
It is true if your the number of pages in your<BR>
pagelist set before filtering on categories is a<BR>
large percentage of the number of page's on your site.<BR>
<BR>
On the other hand, if you have say, a small group,<BR>
with only about 10 pages in it, and you have specified<BR>
group=smallgroup in your pagelist command, and your<BR>
site has about 1000 files in it, it will actually be<BR>
slower with the current indexing system. The reason I<BR>
suppose is because searching the index file (of 1000<BR>
entries) for the links of your 10 pages can actually<BR>
take longer than simply searching the 10 files in<BR>
smallgroup.<BR>

indexing system.) :(<BR>
