I run a homebrew game server on my Redhat Enterprise server. The game creates a lot of debug output, which I redirect to a text file from the command line when I start the server, for example:

./game >outfile.txt

Problem is, as the game runs longer and longer, the game gets slower and slower. I was wondering -- is it possible that the slowdown could be due to outfile.txt getting very large, say for example, a couple of gigabytes? Does this kind of operation get slower with a bigger file or does it just keep appending to the end with no real slowdown? Thanks!
