slow Hyper V virtual machine after changing the host machine with a more powerful
Posted on 2011-10-19
My scenario is as follows:
I had a physical machine with i7 and 12GB RAM, running the TMG, DC2, and server applications. The application server runs a database SQL Anywhere SyBase see 9.2.
Sybase customers worked well.
Now we have a server with Xeon Intel E5620 and 20Gb. more powerful than the previous we have virtual machines on this computer, the application server is assigned a network card that is not shared with any other virtual machine.
Application server you have 10GB, you can ask more and 6 GB have been assigned to 3 processors.
Now users complain of the Sybase client programs sometimes display when changing them takes a second or two to display options for the dropdownlist, I've seen and it's like take to get the information from the database, once the screen loads then goes fine.
If you run the program locally or from the application server all is well.
My surprise is that changing to a more powerful server which allocates more memory and processors, the results seem to be worse.
Anyone have any idea what could be happening?
All ideas are welcome.
thank you very much.
