Hello,
I have recently encountered extremely slow download of the Image.wim files while in PXE environment.
I have verified that IIS is not being limited and in monitoring the switch port the server is connected to I have getting on between 8-10% utilization of the 1GB port and the Server Resource monitoring is showing a max network at 100Mbps. The Image.wim file is 8.2GB and is taking roughly 6-7 hours to download.
This is not a question about TFTP transfer of the Boot.wim and have in placed the Reg change to increase the block size.
I have verified IIS default site has no limit on transfer.
Client BITS settings are not enabled on Default Client settings.
Current Environment of Distribution Point
Virtual Server running on ESXi 6.0
Windows Server 2012 R2 Standard OS
SCCM 1606 Distribution Point Role
8.0 GB RAM
Virtual Server running on ESXi 6.0
VMXNET3 Ethernet Adapter: Speed 10.Gbps, Driver version: 1.6.6.0
VMware tools version 10.0.0.3.000743
I have attached an SMSTS,log which verifies the proper Distribution Point is being contacted for the content. This log shows the Image.WIM download starting at 10:22 AM and the Apply Operating System not starting until 5:05PM. This may be a VMware/Server issue, but wanted to verify this could not be related to SCCM prior to sending this issue up the ladder. If anything other information is needed please let me know, I have been searching the internet and I am leaning towards the VMXNET3 adapter and VM tools upgrade.
Thanks for any help.
