We seem to be having random speed issues with CD (now on 1.3.4). Server is Windows Server R2 2012, running windows DHCP (issues were also present on TFTP32 before switching).
Have a group of 12 PCs and attempt to multicast and get only 20MB/s when deploying. Restart the whole server, and get 6GB/s using the same group, switches etc.
In further testing, we seem to also encounter random issues downloading core scripts. Either manually restarting or waiting for the PC to automatically restart allows the PC to get the script fine.
We are still troubleshooting to find a definite pattern, but if we seem to encounter a script download problem, we appear to get poor speeds from the subsequent multicast attempt.
The quantity of PCs seems to be irrelevant, however we seem to be more likely to hit a script error with larger numbers, which may be an issue or just chance.
Any ideas? Happy to provide logs etc if you can point me to what you need.
Script error text is:
Downloading Core Scripts
Could not download script
Response code 500.
