[dba-VB] Multi-project solution

Hi John:

I do not know what you are doing as some applications I have built have been
tested at over a hundred users with no loss in performance. I could imagine
that several hundred users might adversely affect performance but not just a
few... it just does not make sense.

With the horse power you have and just starting a few applications, the
system should barely register the initial connection.

Something sounds very wrong.

Jim

There are no projects that are stable.  I just hired a fella to work with me
because I have so much 
dev to do I couldn't do it all myself.

The version control system repository is on the server because the server
has mongo raid 6 arrays 
with room and redundancy.  I never really realized that things would slow
down so much when accessed 
from workstations because I never developed this way until now.

The solution code all operates against the server, IOW it causes execution
of stored procedures that 
perform massive table operations on the server.  Likewise the files imported
/ exported are stored 
on the server because... there is a massive RAID 6 array with storage and
redundancy.  Not to 
mention that the server itself has massive memory etc.  That is only getting
more so in the future. 
  My server is about to go to a truly massive (to me) system with 16-24
cores and 32G-64G of RAM.

So I set it all up to just be on the server and I used remote desktop to get
in and work.  That 
really isn't optimum having the actual application EXECUTE on the server, or
for that matter to have 
two people actively developing code on the server -  that is what
workstations are for. But the 
server is the most powerful machine in house by far so storage and SQL
Server processing is and will 
continue to execute there.

It isn't clear why the debug stepping is so slow, however it is certainly
not unique to me.  I 
Googled it and found just dozens of threads on dozens of sites regarding
this issue.  It also isn't 
clear that Projects are the reason per se for the slow debug stuff.

As long as everything works, using many projects is not too big an issue but
when you start 
repeatedly searching through all of the project properties dialogs it
becomes tedious.
