Build Status

what is this?

the greatest website to ever fit in a single TCP packet


  • HTTP compression: choose DEFLATE over GZIP because most browsers accept raw DEFLATE output without a header or checksum so it's shorter/faster. #yolo
  • send response immediately after TCP session init: avoids 1 round trip (not to spec, seems to confuse Chrome results in Wireshark).
  • SO_BUSY_POLL: asks the kernel to poll for packets for a given amount of time.
  • TCP_NODELAY: disable Nagle's algorithm.
  • echo 1 > /proc/sys/net/ipv4/tcp_low_latency: TCP stack makes decisions that prefer lower latency as opposed to higher throughput.
  • favicon: reduced gif to 1/2 original frame count, applied lossy LZW compression.
  • HTML mangling: closing tags are for losers.
  • bespoke webserver written in C
  • remove GIF comment extension block, saving 36 bytes (thanks Samy Kamkar)
