HP will offer its migrating customers another update on the performance of migrated applications in a few weeks, but this time the advice will be available via a Webcast. The last time HP presented "Performance of Migrated HP e3000 Applications" the engineering advisory came as part of a paid registration to the HP Technology Forum. On December 6, the HP user group Encompass will offer the talk, usually presented by HP's Kevin Cooper, in a Webcast from the Encompass Web site.
HP has given this talk at least once a year since 2001. It's updated with customer migration experience which HP gathers during its migration engagements with HP 3000 sites.
The hour-long Webcast at 2 PM EST does not promise migrating users a definitive forumula for their figuring. Many migrating 3000 sites want to know how much hardware to purchase to get the same level of performance as what they now get from HP 3000 systems. A lot of what has been reported on this subject can be shortened to "It depends."
The Encompass/HP announcement sets expectations accurately. "From this talk, hopefully you will understand why your questions about migration performance can’t be answered with a single number!"
We're not sure if HP's got new data to offer on this subject, or simply wants to restate what's been discussed in the past. Cooper has been giving this talk for years; the presentation's bottom line in the past has been "databases are the most important element in estimating how fast your migrated app will run. A close second is your app's dominant language." These results have given applications moved to Marxmeier Software's Eloquence database and AcuCOBOL's COBOL the edge in performance.
To compare stories from HP on the subject, you can have a look at our 2001-2005 reports from Cooper's very sound presentations in stories from The 3000 NewsWire (do a search on "kevin cooper" + application in our Search Engine) as well as from our NewsBlog in December of last year
n discussions about migrating applications off the HP e3000, a common question is, “How will these applications perform on a new platform?” Users moving off the HP e3000 need to know what size system will be required to run their migrated applications. This webcast will explore what is involved in figuring out how an application will perform when it is moved from MPE/iX to another operating system like HP-UX, Linux, or Windows.
This presentation will look at the different components of a migrated application, and investigate the performance implications of some of the available alternatives for each component. HP takes a look at some of your choices in hardware, including platform, CPU speed, number of processors, memory, and disk. Cooper also examines some of the performance differences in software, such as operating system, language, database, the I/O and networking layers, and the user interface.
