Then are SERIOUSLY up against it. Very large geometries and
javascript without some kind of tile server is total nightmare.
Browsers just cant hack it, nor can internet data transfer rates.
How were you proposing to fetch the vectors?</div></blockquote><div><br></div><div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">You may misunderstand me.

That's another question which confusing me, the smaller the zoom level, the more the features, so we consider to simplify the features, but we are not sure it should be done in the client or in the server. <br>

GeoJSON files? You
might want to look at what UTFGrid can do for you but you still have
the problem of fetching large no. of vectors across the internet in
a verbose format, and drawing them in js. You cant rely on everyone
to have Chrome. More than 500 vertices is enough to choke IE. I
think you have to look at some kind of tile server. I dont quite
get what you mean by "import" a tile server into your project
either? Are you looking at off-internet standalone? There are tile
server options for this kind thing.<div class=""><br>
