Re: filesystem considerations

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 ?
For sequential writes, maybe. (But in that case, JFS with extents is still
faster.) For random, probably not.
A LMBD database is a big flat file isn?t it ?
Yes.
Extents are very interesting
with that kind of files, aren?t they ?
For sequential access.
Did someone try it ?
