Bug Description
Steps To Reproduce:
1. Create environment with 200 servers.
2. Bootstrap 200 nodes (using ipmi)
3. Wait
Expected Result:
All 200 nodes will bootstraped to Fuel master node as slaves nodes within 10 minutes without problems.
Observed Result:
Fuel required 2 hours to bootstrap 200 nodes. Some nodes timed out and required 3-4 reboot cycles (happened automatically) to finish bootstrap process. There are some performance issues in tftp protocol, and all servers can't bootstrap from one Fuel master node in parallel. Also tftp forked too many processes as every tftp client require single tftp process

via HTTP.
