Performance and scalability: WebSphere App Server on Intel
I'm interested in justifying using Intel vs. our companies standard, AIX IBM p/series, to run WebSphere. Are there any case studies or experiences available?
Many vendors packages support only Intel and building an infrastructure is a difficult undertaking.

plz refer to the above link ... u get find some info regarding the
test perfornamce issue and do pls send me email regarding the "result"
of the perfornamce to <instrumantat at netscape dot net>

You can get a good idea of relative performance using SPEC JBB benchmarks. The Intel Kit for 2 way XEON compares well to SPARC and POWER-PC at a fraction of the cost.

Many vendors packages support only Intel and building an infrastructure is a difficult undertaking.You can assume that processor power is more or less the same between Intel and other processors, such as SPARC. The decission about using intel vs. other architectures should be substained in other parameters, such as:
. reliabitily. This affects to important issues, such as 24x7 availability, hot-replacement of hardware, etc.
. amount of information. You should expect better performance in other architectures (such as UNIX, zOS, etc) in topics such as I/O throughput. An intel server could have the same processor power than a mainframe, but it never is going to be able to move the same amount of information than a host is able to move in the internal bus (information between the cpu and the memory, the disks, etc.).
. third party tools. If you only use WebSphere it could be ok to use any architecture. If you use a specific third party software (a JDBC client, a security tool, etc.) maybe you are going to be constrained with the supported hardware of this third-party tools.

Trust me, you don't want Java on a Zseries. I do. It sucks really bad.
Trust me, you don't want Java on a Zseries. I do. It sucks really bad.Yeah ! WebSphere for zSeries has a very bad reputation... ;D
Nevertheless, IBM says right now that the very last version of WebSphere for zSeries is the ONE that we should start considering, because it is starting to perform on a decent way. Has anybody any experiences with this last version?
