Learn how mount options such as
affect Kafka performance.
Linux records when a file was created (
mtime) and accessed (
atime). The value
noatime is a special mount option for filesystems (such as EXT4) in Linux
that tells the kernel not to update inode information every time a file is accessed (that is,
when it was last read). Using this option can result in write performance gain. Kafka is not
atime. The value
relatime is another mounting
option that optimizes how
atime is persisted. Access time is only updated if
atime was earlier than the current modified time.
To view mounting options, run
mount -l or
