- Welcome to JACK, the Jack Audio Connection Kit.
-
- Please see the website (http://jackit.sf.net/) for more information.
-
- NOTE: If you are using reiserfs or ext3fs or anything except ext2fs
- for the directory where JACK puts its temporary files (/tmp by
- default), then the JACK team recommends that you do *one* of the
- following:
-
- ----------------------------
-
- Mount a tmpfs on /tmp. You should have a lot of swap space available
- in case some programs try to write very large files there.
- In your /etc/fstab add a line:
-
- none /tmp tmpfs defaults 0 0
-
- You'll probably want to reboot here, or kill X then 'mount /tmp'.
-
- ---- OR ----
-
- Alternatively, you can do this without affecting your /tmp:
-
- # mkdir /mnt/ramfs
-
- [edit /etc/fstab and add the following line]
- none /mnt/ramfs tmpfs defaults 0 0
-
- Then add --with-default-tmpdir=/mnt/ramfs to the JACK configure
- line when you build it. No clients need to be recompiled.
-
- ------------------------------
-
- Failure to do one of these could lead to extremely poor performance from JACK,
- since its normal operation will cause bursts of disk I/O that are
- completely unnecessary. This suggestion can also be used by ext2fs
- users if they wish.
