CRM is slow

[Former Member]

Dear Gurus,

I would like to ask for advise and help here.

Our CRM Development is quite slow compared to CRM Production.

Our CRM is on EHP2 FOR SAP CRM 7.0.

SAP Kernel : 720_EXT_REL

Database Client Library : DB6_81

created in  :  NT 6.0 6002 S x86 MS VC++ 16.00

created on  :  Jan 16 2013 16:44:54

Support Level :  0

Kernel Patch number : 401

Source ID  :  0.401

DBSL Patch No. : 323

ICU Version : 4.0.1 Unicode Version 5.1

libsapu16 Version : 2.0025  Jan 16 2013 13:18:43

OS for CRM Dev:

Windows 2008 R2 Standard

CPU 2.67GHz

RAM 12GB

OS for CRM Prod:

Windows 2008 R2 Standard

CPU 2.4GHz

RAM 30GB

Conditions:

1. Our CRM Production, it has 30GB RAM but it is being accessed by around 50 users per day and the performance is ok.

1. However my CRM Dev, although it has only 12GB RAM, but it is only being accessed by 2 people of SAP CRM Consultants and the performance is slow.

1. Usually the CRM Dev will be slow in the morning when no body accessed the system yet, and the first CRM Consultant who accessed the CRM system will experience slowness both in ABAP and also Web, but afterwards, the slowness will become better a bit.

Do anybody have any advice?

Thank you in advance.

Regards,

Stephan

Hi Stephan,

Be happy, as long as your CRM production system's performance is ok.

Changes in a development system lead to buffer invalidations. Good performance often can only be achieved in a warmed-up system (nametab and table buffers filled, shared memory objects instantiated, no invalidations due to development / imports).

How much of the 12 GB RAM are reserved for the ABAP Extended Memory?
Show a screen shot of ST02; there should be no swaps.

Hi Stephan,

ABAP memory looks ok ("MaxUse" for Extended Memory << "In Mem"), but program buffer and Generic Key table buffer could be a problem. But in a development system one normally cannot avoid object changes that lead to program / table buffer invalidations.  Therefore rather concentrate on application performance in a consolidation or production system.

Dear Randolf,

Thank you for the great help. I will consult this issue with my SAP CRM Consultants.
