Hello listers, Over the weekend, we migrated a couple of large SAP systems from SLES10 SP4 to SLES11 SP2. These are large SAP application servers (22GB). Our SAP folks have a transaction that can be used to measure SAP response time. Our servers are grouped by the applications they run.

Re: 32-bit vs. 64-bit performance & resource consumption?

>From a life-cycle management perspective, do what David said and go 64-bit. >From a performance perspective, build both and MEASURE the results. (Of course, you'll be running on a 64-bit kernel in most cases, so getting a pure sample will be tricky.) On Wed, Mar 27, 2013 at 10:37

32-bit vs. 64-bit performance & resource consumption?

mption - but a fully loaded customer configuration may have hundreds of instances running at any one time (persistent, once started they stay alive), so any performance and memory consumption differences between 32 & 64-bit c

New Performance White Paper: z/VM 6.2 Live Guest Relocation with Linux Middleware

z/VM 6.2 Live Guest Relocation with Linux Middleware Version 6.2 of the IBM® z/VM operating system introduced the concepts of a z/VM cluster and Live Guest Relocation (LGR). This project shows the impact of live guest relocation on a Java application and gives recommendations for configuring z/VM

Re: Performance effect of multiple virtual processors

No, it won't wait.  z/VM will dispatch the guest on a single logical processor if necessary. Keith Gooding wrote:Hi all,   Suppose I have a linux zVM guest with n virtual IFLs running in a z/VM LPAR which has n dedicated IFLs. If the guest is dormant and becomes eligible to run again ( eg I/O c
