Just because we are the fastest filesystem does not mean that it will be
easy for us to get in. Actually, it makes it harder to get in, for
reasons I'd prefer not to state. This week would be a good time to ask
for reiser4 to be merged in as an experimental fs if you want it.

Hello,
Sorry if this is common knowledge but how do you go about making a request for a
feature in the kernel?

Look for a thread on the linux-kernel mailing list titled:
Re: 2.6.9-mm1
and join that thread which discusses reiser4 with comments suggesting
reiser4 would be nice to have.

I responded. Meant to do it on Friday but my brother is in town and I
got distracted.

[-- Attachment #1: Type: text/plain, Size: 1011 bytes --]
I thought my personal benchmark might interest some of you. Attached is a plot
of running a simulation of a commercial wholesale application.
Each iteration in the plot is a complex transaction (i.e. place an order for a
(possibly new) customer). The Y-axis says "transactions / second" but should
really read "single data base action / second", where access is "read",
"write" or "update" a record. The X-axis is one point per1000 iterations.
At the beginning of the simulation there are about 1 MB of data (in 16 files).
At the end of the 200000 iterations there are about 750 MB of data.
Reiser4 is considerably faster than Reiser3. Puzzling is that the advantage
decreases somewhat as the data grows.
Most puzzling is the yellow line "ReiserXXX" which is considerably better than
the line labled "ReiserFS". "ReiserXXX" is, wait for it, "Reiser3" on a 2.6.5
kernel. Is it well known that 2.6.9 is slower than 2.6.5?
Any comments welcome.
Malcolm Agnew
p.s. The data base engine is my own.

Hmm, I see nothing attached

How much RAM is there?

Would you please test for reiserfs under the same kernel?
