Subject: [gentoo-user] linux' IO performance sucks

1 Hi,
2
3 sorry for the silly subject, but did you ever experience the following?:
4
5 i have a fileserver, i copy a file to it - let's say 600MB.
6
7 So about every 200MB (i guess the linux box writes the data into the
8 cache in the RAM first) linux writes the harddisk. But during that time
9 - during the time it writes that 200MB to disk, there is no chance for
10 any other IO. I'm playing an mp3 from the very same fileserver. It stops
11 playing, because the machine does answer the read-requests.
12
13 So what's going on here?
14
15 Why does Linux write so huge amounts of data to the disk? Why does Linux
16 not stop writing for a while to fullfil the read-requests? And so on ...
17
18 Any idea, on how to imrpove that?
