C MultiThreaded TCP Server Handler - Streaming

Hello, I want a simple but powerful application in C that will be able to work on all Linux 64 Bit Systems. This application must be able to listen to a specific port and receive connections using Threads . Must be as fast as possible and use as low resources as possible because i want to use it for streaming so speed and low memory matters. I will provide examples that the program must be able to handle: ./server -h [login to view URL] -p 8080 -f /tmp/[login to view URL] -b 4000 -h => HostName to listen to -p => Port to Listen To -f => the file source that this program will contain. If i make a conneciton to 8080 for example i should be able to read that file and get its contents. It should be able to read from pipes as well. For example -f - should be able to read from fd0 etc. -b => the buffer size in kb. The total Size can not exceeded this value. If for example my file is 10 MB and the buffer is 4MB , it should transfer the 4MB, then remove the first bytes and add the remaining MBs. I want to use this application in live streaming, thats why the buffer size is important. I dont want to save the whole video file but only specific size each time so that the video can continue. I want it as fast as possible and be as fast as possible. Do not use C++ cause of speed. I want it in 2 Days MAX. I will Pay when i will be sure that the program works as described. Thank you
