Sean, I don't recall any mention of increasing the polling threads. I reread my case notes and it says the polling threads "were constantly hitting the max of 40" (not 20 as I misstated earlier). What we did in response was to re-balance the device load much more evenly between our 2 DSSs (5500 on one, 4500 on the other). But it's not like we were noticing any performance issues that triggered this review. We simply wanted to do a health check before upgrading to v9.2.
We have a parallel set of v9.2 TEST servers monitoring the same set devices. CA is assessing their performance as well. On our v9.2 servers (equal in horsepower to our v9.1 servers) the only troubling symptom that we are seeing is that when we go to the Locator Tab and pull up the list of all devices, it takes about 50 seconds for that to populate fully. It's something like 15 seconds on our v9.1 servers. Maybe this is a non-issue but hopefully the perf review will tell.

We have about 1900 devices on that landscape and we rarely run out but when we have on other landscapes we have increased it and noticed the difference, using packet captures to verify. Are you experiencing any issues because of it using the 20 threads, like slow polls missed polls etc? You can also tweak the polling groups, but that gets a bit lower level. Did they mention changing the max threads to you after their review? Regards, Sean Sean Carnes Cablevision Systems Corp.

Until it is made multithreaded so it can use more than one processor there will always be that bottleneck. Patrick ________________________________ From: Miner,Eric D.

One thing that came out of that review is that on one of our DSSes (managing about 8,000 devices) Spectrum had max'd out the number of threads (20, I think) that it could use for polling. So it seems that no matter if the SS was 64-bit and had tons more memory available, we would still need to move some of the workload (managed devices) off to another SS. But maybe there are other advantages SS on 64-bit other than lifting the memory ceiling?

(Legacy KB ID CNC TS29305 ) SPECTRUM 9.0 will install and run on 64-bit OS that are supported (listed above). However, they will run only as a 32-bit application and therefore will not take advantage of extra memory resources beyond what a 32-bit application of that platform allows. Spectrum 9.0 with Solaris x86 is not supported. CA plans to add support in Spectrum 10.0 to allow for 64 bit OS to be supported.
