XI performance

[samantha_nez]

Hi,

We are analyzing the performance in XI 3.0 and we have several questions about this subject.

1. In presentation layer, is it advisable to use XI 3.0 between a front-end and a back-end? We get a bad performance and irregular runtimes when we run this scenario. Why?

2. We would like to know too when we must use asynchronous scenarios or synchronous scenarios according to performance. We have read that synchronous mode is not advisable...

3. At last, when we use BPM, we have seen that its performance is not too good.

We have set up XI according the tuning guide from SAP Marketplace.

I will be grateful if you provide our with some weblog or another reference too.

Thanks in advance,

Samantha.

<b>1. In presentation layer, is it advisable to use XI 3.0 between a front-end and a back-end? We get a bad performance and irregular runtimes when we run this scenario. Why?</b>

presentation layer is where ur GUI is loaded and executed. the reqyest made from the presentation layer is handeled and serviced by the dispatcher. so u need to ensure that the Network connectivity is gud enough. Also u may need to check the RAM size

<b>2. We would like to know too when we must use asynchronous scenarios or synchronous scenarios according to performance. We have read that synchronous mode is not advisable...</b>

depends on the scneario. when u expect a acknowledge from the recv on the processed meesage then u may need to configure sync scenarios. it might be inevitable attimes. performance of sync steps depends on target systems

<b>3. At last, when we use BPM, we have seen that its performance is not too good.</b>

BPM gets executed in the BPE engine and every mapping step needs to be called from BPE to j2ee stack. to tune the performance we might need to do with mapping. refer this check list:

Hi Samantha -

A very good reference on identifying performance issues/bottlenecks is contained in Note 894509 - XI Performance Check.

Also, here a some recent blogs:
