I’ve recently set up FOG and I’ve noticed it takes about 30 minutes to download fog/kernel/bzImage and the file after that (I don’t remember exactly what it is). I upgraded the BIOS, that doesn’t seem to have changed anything, since I read that might cause the problem.
Here’s my setup:
TestA ========== FOG Server — Client 1
TestB ====/ ±- Client 2
±- Client 3
±- Client 4[/CODE]
The === is our corporate network and — is our isolated network. Everything is gigabit networking.
The FOG server acts as a NAT so that the clients can get out the corporate network. When I download bzImage using TFTP from the FOG Server to Client 1, it will download at about 60KBps. When I download the same file from the same server to TestA, it goes about 1-2 MBps. I thought it was a problem with the isolated network. But then I tried to download a different file: I downloaded a file (not using TFTP) from TestB to Client 1. And it went 1-2 MBps, too. So it seems that TFTP is only slow on the isolated side.
First Test: TFTP bzImage from FOG Server to Client 1: 60KBps
Second Test: TFTP bzImage from FOG Server to TestA: 1-2MBps
Third Test: SMB (Windows shares) from TestB to Client 1: 1-2MBps
What could possibly cause TFTP to be slow only for the isolated network?
