Thank you. Are those files located within one dir or do you use a hash
structure like squid cache does?

There's only a shallow hierarchy (for functional, not for distribution
reasons), so the relevant directories have thousands of files in them.

I think after the "ext2"-age no serious file system ever had
a real problem dealing with lots of files in one directory -
or do you have contradicting information?
