Attaching Tables (OpenInsight 32-bit)

We have a customer who when logging on to the OI system and attaching tables is taking a very long time for each sucessive workstation. The W/S are a mix of XP Pro, XP and Windows 7 the server is a VM running Windows Server 2008. They have been running this config for months and only started having problems this week. Any help would be much appreciated.

Can you verify the disk access times at the server? Perhaps the configuration hasn't changed but maybe the virtual disk has changed. OpenInsight is very sensitive to disk latency. I've seen virtual servers in the Amazon cloud give some very poor disk performance at times while other times give better than average performance.
HD Tune is a tool you can run at the server to do a a benchmark of the IO performance. Run a "Random Access" read test with transfer sizes of 512 bytes and 4 KB. If you run the test multiple times back to back you may see the performance increase if the disk cache kicks in. For example, on a typical Dell PERC 5 RAID with a 8 disk SAS 15k RAID 5 array the average operations/sec is 350 but after the second and third attempts the disk cache kicks in and the operations/sec jump up to 8000+. Your virtual server disk or SAN may be saturated for that server as users login.
When the users start to notice slow performance can you launch OpenInsight on the server console and detect any difference in performance? If your console session runs quickly you may have a network bottleneck. If the console session runs just as poor then I suspect a disk issue.

Two things spring to mind for me.
One is Citrix, and I realise you did not mention it, but with Citrix the subsequent users find speed performance issues when starting up, which is resolved by making the Session Id unique. Probably not relavent, but mentioned in case its worth a try.
The second is with the network drive mapping.
I have seen problems with the client taking a long time to figure out the drive path to the server.
This is seen even in Windows Explorer when you try and locate the network folder for the first time, it can take some time to resolve, and once resolved is up and running fine. Check if the IT department at the customer have changed anything recently, and it may give an indication.

On a 'CLOUD" system can you still install the LH Service.
Should I just be looking at a 'Cloud' server as exactly the same as an in-house server.?
I just have this thing at the back of my mind saying that cloud is only setup for SQL based system (or was this the case I havent caught up).
I have a prospective client for a system I developed that is moving to the cloud, all I could say was try installing the demo and see.
Another thing, I also have requests re 'can it run on an IPAD', is the only way to do for an OI app (yes, I know O4W will work) this via Remote Desktop or 2X.?
Do you still get the 'keypad' showing for data entry (sorry, don't have one)?
