I discovered that pulesaudio does a lot of I/O during boot (about 5 seconds).
Those la files doesn't exist in fedora, so pulseaudio should not try reading them, thus save I/O time and gain some speedup.
Comment 1 Brendan Jones 2011-04-10 08:11:40 UTC 
The I/O you are seeing is libtool loading the .so of the same name.
Comment 2 Elad Alfassa 2011-04-10 08:20:35 UTC 
Then why are all those "No such file or directory" errors? Those useless fopen calls can take 0.05 seconds each, and with 91 calls, it's 4.55 seconds of I/O that could be saved.
