FSP historyFSP development started in a very old days. From source code and man page time stamps we can see that working and prototyping FSP started in 1988.
FSP versions 1.0 and 2.0 was born in Dec 1991. After that two first releases FSP goes to the active life.
Active era of FSP development ends in May 1993 when last official version 2.7.1 was released. After that then was some work on FSP in 1995 and which ends with now famous FSP version 2.8.1b3 in March 1996. This version is used on some servers today because Debian Woody has it, but 2.7.1 is still used on some forgotten machines in univesities.
I have released 2.8.1b4 in 2001, which was just some bugfixed version of 2.8.1b3 untouched from 1997 when I ported it to OS/2 (It was just a private port). Active working on FSP again starts on 25 June 2003 where Version 2.8.1b5 goes out.
I have rewrote a major parts of FSP server code for higher performance, because old code uses too much syscalls (about 10 for serving 1 packet) and fixed some very old bugs in FSP code.
After looking at FSP access stats on Freshmeat it is clear that FSP is live again.
