my experience

  1. GW backend troubleshooting is more difficult on windows than Linux/nw groupwise
  2. very difficult to get bug fixes fixed on windows
  3. GW on windows IS supported, but is NOT recommended. Trunk of the tree is running GW on Linux.
  4. I recently viewed one of my customer's POA stats. Over 210 days for a Post Office up and running on Linux! Rock solid stability and performance!

Other's experience

"In our environment, we did find some performance issues with running GW on Windows -- which the customer is working around. My customer is running a 6 or 8 node Windows cluster with 5 POs, a domain, and other pieces on it. They share a SAN with windows file & print cluster as well. The F&P is running low disk utilization. The GW resources run very high (>= 95% disk utilization based on I/O). Given all of the GW resources are sharing the same spindles, they started getting hurt after a while as mail built up -- and backup times extended out 300%-500% of original and of that on NetWare. Go figure! Their resolution has been to move to faster drives (15,000 RPM) in the SAN and larger stripes -- 15 disk arrays vs. 4-7. Their performance has gotten backups down to < 4 hours -- vs. the 14-20 they had been.

They also purchased a tool to help keep the disk de-fragmented. I don't know how much it will help in the long run but they were > 60% fragmented after a year of uptime."

  1. recap
    1. Performance issues (unhappy end users?)
    2. High CPU utilization
    3. Slow IO disk performance on windows
    4. Bad disk fragmentation
    5. Slow backup performance
    6. Poor high availability solution

How about virtualizing SLES inside win2008, and having the sles serverrunning GW?

Here are my thoughts on this:

  1. uncommon configuration, not trunk of the tree. Most customers do not run in this configuration.
  2. one expert says, so long as it is NOT a PO server...given the IO requirements
  3. The POA MUST have 500 mb IO, otherwise GW users will be unhappy with the performance
  4. Often, when there are support issues, we can only troubleshoot the application...while there are many other factors such as OS/hardware etc, now we add another layer of complexity.
  5. still researching
