WMS layer - correct. I am using version 1.9. Mapserver is running as
CGI and hums along nicely answering WMS requests. Things slow down
when tilecache makes the WMS request. Subsequent requests to tilecache
are snappy but it seems to be taking a long time to do the WMS
request. <br>
<br>
I installed tilecache and altered my apache2 config to <br>
AddHandler cgi-script .cgi<br>
Options +ExecCGI<br>
<br>
so I assume this means it is running as Python CGI. So I guess the
slow part is the CGI execution for each request. <br>

to create. If I look at the apache log and mimic the requests the tile
cache is making to the WMS the requests are returning images in
subsecond response times as is expected.
The server it is running on is not under any load and I am trying to
work out where the throughput blockage is. I am getting results such as
[20.4531s : 0.048/s] 52/252 from the seed program.

I'm guessing this is a WMS layer? MetaTiling in use? Any other strange
setup? 1.9, or SVN? Running on the server as CGI, mod_python, other?
