Hi,
I have some large ext4 filesystems with large numbers of files in them and performance
really sucks. After inactivity, a simple ls takes minutes to complete. I'm pretty sure
the drive is now powering itself down due to this inactivity.
Are there tuning parameters that I could alter that would keep more of the filesystem
meta data in memory? It looks like the data slowly migrates back to disk and as a result,
takes minutes to fill back up enough to respond.
Regards and THANKS for your help and your time,
