Max Concurrent Threads for SRS1.0 SP2

How many concurrent threads will SRS 1.0 sp2 spin up to handle concurrent subscriptions? Is the alogrythm documented anywhere? It appears that changing the MaxQueueThreads from zero(Default Value) should have an impact on the number of threads. If so are there any MSFT best practices around changing this setting?

Thanks

If MaxQueueThreads = 0, SSRS will spin up as many threads as it thinks it needs to process all the subscriptions -- but I've never seen (internally or externally) this decision making process documented.

There also is no "patterns and practices" type guidance on changing this value...that being said, lots of small reports generally do better with a higher number here (so we can run multiple, quickly completing reports at the same time), while large reports like a smaller value (because we can run fewer big reports at the same time without RAM contention issues, I guess).

I played around with some "subscription tuning" scenarios a while back...You an read about what I learned here:

After a little research, it looks like the main inputs into MaxQueueSettings are # CPUs and amount of free RAM...Thinking more about this, I suppose you could just use perfmon and watch the number of threads reportserverservice.exe and/or w3wp.exe spins up during heavy subscription activity along with RAM they utilize...then play with MaxQueueSettings

Matrix BackgroundColor

Hi all... again.
I am still having problems setting the backcolor of my matrix cells.
I am able to get a handle on eachcell as the rows and colums have vlaues
associated to them.
E.G.
I have four columns and 4 rows. these will never change.
The code below access the bottom left corner of the matrix and this works.
all i want to do is do 16 if statements to manually set the color.
The problem is when i go to add more if staements. the report jsut doesnt
compile.
How do i add 16 if statements. what is the syntax.
iif(( Fields!PotentialPoints.Value = 25)AND(Fields!PerfPoints.Value = 25),"RED","Yellow")

Thanks in advance,
Dave HuntIt may be easier to use VB Switch function.
