before you do that, you need to make sure your database is not the
bottleneck. It is doable, and relatively simple.
You can add 10 witango machines, but if your db is the bottleneck, it
won't help at all.
You can do iis, as one server, hitting your two witango boxes, this
is easiest.
Or you can setup a IIS server on each witango box, so that each IIS
server can hit both witango servers, then just use round robin dns to
distribute the load. Then witango will handle making sure the request
that comes in, goes to the right witango box. The key is, make sure
both IIS machines, have a witango load group that is identical.
Another solution, and how I do it, is you have IIS on any number of
servers, and witango on any number of servers. Each IIS server has an
identical witango load group, so they see all witango servers. DNS is
roundrobin to the iis servers.
In my testing, I have found that 4 single processor witango machines,
are more efficient than a 4 processor witango machine, of similar
processors. On the quad machine, they may have 4 processors, but they
share the same nic, poss. the same memory, the same disk system, etc.
Redundancy is also much better on mult single proc. machines.
One more thing, if you notice your witango processes hanging at 100%
for periods of time, and it is not because witango is doing some loop
or heavy process, it is most likely your db not responding fast enough.
Are you using v5.5?

Here's a general question that some of you have probably run in
to before and I need some direction. We currently have Witango
professional running on a Windows 2003 quad server accessing a SQL
database on another server. At times, due to load, we are seeing
the Witango server slow down. Now, our web server is also being run
on this machine. What I would like to do is to purchase another
Witango professional license, and move our current Witango
application server to another box, and the new server to yet
another box. This would give us two Witango application servers,
accessing our SQL server and handling calls from our IIS server.
Four boxes in all.
First question, is this doable?
Second question, how would I set up IIS to determine which box
to send queries to?
Third question, shouldn't this help our response time assuming
the database is not the bottleneck?
Thanks for your advice!
