Superfetch was keeping an index of file relationships in RAM and pre-loading files you were probably going to use next. It didn't ping your network at all, but it could easily eat up a ton of disk resources and RAM. It was really only an issue on old 5400rpm laptop HDDs from what I remember.

Might be thinking of windows search indexing.
