I am implementing a new SAS Visual Analytics 7.4, running on a Linux virtual machine (non-distributive). After the initial installation, the performance speed of using SAS VA is fine, although not super-fast.
From the default installation, a “Public LASR Analytic Server”, a “Visual Analytics Public Data Provider library” and a “Visual Analytics Public LASR library” are created.
We are going to have roughly 30 separate groups going to use VA. I would like to achieve:
So I created a separate “LASR Analytic Server”, a “Data Provider” library and a “VA LASR library” for each of the initial 7 groups that will be using VA. I basically mimic the “Public’ setup mentioned above.
But now the performance of the VA is very slow, each mouse clicks would result in a 10 seconds wait, even with only one user using VA.
I am wondering what I did wrong and how do I achieve my above 5 objective without the substantial performance impact. Will vertical clusters mentioned in SAS 9.4 Web Application: Tuning for Performance and Scalability, Third Edition solve my problem? Right now I am not using cluster at all, just one ‘SASServer1_1’ from the default installation.
Thank you very much.

Like I said on the track, you did everything right. Your middle-tier server might be underestimated, so I will move your track to the middle-tier support.

I forgot to mention that in my initial installation I specified the system size to be "Medium System' in the SAS Deployment Wizard".
