Hello,
I read a long time ago theses very interesting benchmarks : http://symas.com/mdb/microbench/july/.
It seams that ext2 is the fastest filesystem for asynchronous writes.
Do you think an ext4 filesystem without journalisation but with extents could be faster ?
A LMBD database is a big flat file isn't it ? Extents are very interesting with that kind of files, aren't they ?
Did someone try it ?
Regards
