JDE 9.0 TR 9.1.5 on MS Hyper v 2012

Can someone share their experience running E1 on Microsoft's VM? We recently migrated from all physical Windows 2008 JDE 9.0 TR 8.98 to 9.0 TR 9.1.5 on MS Hyperv 2012. Enterprise and DB performance statistics are indicating all should be fine but UBEs are taking twice as long to complete compared to the all physical environment.

You might need a Technical Audit and Performance Evaluation. There shouldn't be a significant decrease in performance to the degree that you're stating - BUT :

1. If you're using EXACTLY the same hardware between the "baremetal" instance compared to a Hyper-V instance, you will definitely see a performance tradeoff (approximately 20% based on benchmarks I published about 6 years ago).
2. You're not comparing apples to apples - it sounds like you went from Windows 2008 to Windows 2012, and upgraded the Tools Release from 8.98 to 9.1.5.x - so you've made some changes to E1. Check logs, and ensure that everything is as "fast" as possible !
3. When you refer to the UBE's slowing down - are these long running UBE's ? ie, are you having an issue with, say, a UBE running 1 hour in your baremetal and 2 hours in the virtual environment ? Or are you looking at UBE's that took 30 seconds and now take 1 minute ? Short running UBE's taking longer might be indicative of a JDE.INI change - but long running UBE's are indicative of overall performance issues. Need some clarity on this.
4. What did you do with your Database ? Is it running Oracle or SQL Server ? What versions ? Where are the disks located ? Most performance issues end up being a database performance issue - for example, the database files are placed onto a RAID 5 disk instead of RAID 10 or something similar. If you're placing the files onto virtual disks - then that could be an issue as well. You might be seeing good performance with processes that can be retained in memory - but as soon as disk access occurs, you might have latency issues.

So, the answer is that you need to investigate more thoroughly, provide more details - and, if you're seriously concerned about performance in a production instance, hire a specialist !
