class=188523223-07112007>We have been given a requirement to support 5000
simultaneous users. What we are finding is that MapServer bogs down
around 400 simultaneous users on a test machine. It looks like
it is likely slowing because of the threading issue.
We haven't tested on a production machine but are estimating that it
should support double what are test machine could handle (double the
processor and RAM). So at least 800 simultaneous users. Divide
that out with the 5000 and we need a minimum of 6-7 web servers supporting
MapServer. We will certainly scale this as is needed but I do need some
idea going in as to what is going to be required.</SPAN></FONT></DIV>

System Configuration<BR></FONT><BR></DIV>
<DIV></DIV>Hello Bruce,<BR><BR>There is no standard answer to your question. It
all depends on personal or business favour, small issues in maintenance and
so.<BR><BR>I for instance tried to host a mapset at hostGIS, but due to a
strange difference in installation with my test server, the datasets turned up
corrupted on linux. I then decided to purchase dedicated windows 2003 hosting
and set up a mapserver myself with IIS for future use in combination with
sharpmap ans asp.net.<BR><BR>Our mapserver related business is picking up.
<BR>Our mapserver is currently serving about 1000 map requests per
day.<BR>Expectation is that this will reach 5000 within the next month. The main
thing we are currently investigating is setting up tile caching to speed up
request/response.<BR>My guess is that 5 paying customers will turn a profit on
the first dedicated server, currently we have 2. 10 customers may be the limit,
but this is a wild guess.<BR><BR>When we reach 5 paying customers, we will set
up the next dedicated server. This is the approach we are going to take.
Loadbalancing is a webserver related matter. This has nothing to do with
mapserver directly. I have also contacted 52north to set up a secured service
for mapserver. They have succesfull implementations of WSS and WAS on top of
WMS.<BR><BR>So the main question to ask is;<BR>- What do you need right now for
the actual demand? I wouldn't worry too much about growing larger in the future,
this issue will solve itself at that time, look for load balancing when it looks
like it might become an issue. Manage your system(s) with care, watch the stats,
watch the response times per request.<BR><BR>And then decide what to do to keep
on track to fullfill demand. This is an ongoing process.<BR><BR><BR>Bruce Cheney

<DIV><SPAN class=164241518-07112007><FONT face=Arial size=2>Hello all. I
am trying to find a typical system configuration for a mapserver
website. I have looked without any luck (could be I haven't looked in
the correct location). Can anyone recommend a typical
configuration. In other words: do you recommend a load balance
server, # of Application Servers, # of DB servers, etc. I realize this
may be application specific but some general guidelines would be really
helpful. For example, for an application server
where MapServer is the predominant resource user how many concurrent
users could it be expected to handle? </FONT></SPAN></DIV>
