slow performance of multiple SAS LASR Analytic Servers, SAS BASE Libraries and SAS LASR Libraries

Hi,

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:

User data/queries/reports (such as tables imported by an end user and data query/reports created by end users) saved in a separate NFS share, instead of mixing with the SAS configuration installation folder /opt/sas94/sasconfig.
Each group’s data/queries/reports saved in the group’s own folder.
Members from Group A should be able to read/write to Group A’s folder only, and members from Group B should be able to read/write to Group B’s folder only.
Different autoload schedules for different groups.
Group can use the same table names in their own LASR libraries.

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.

Jim

@chenj,

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".

Thanks

Jim

@chenj,

I've sent you a new tracking number for the problem with SAS Web Server.
