Hi folks,
I'm trying to setup some infrastructure to verify whether certain Freenet builds
actually improve fetch performance over time (or not). Luckily Freenet already
provides some methods to generate statistics about fetching performance. This
should give some substance to the claims of some vocal users that "build N was
much better than build N+1".
By comparing samples from different versions and doing some statistics we can
actually determine whether the samples from a specific Freenet version are
actually worse or better than a previous version. Having more people contribute
data will allow us to know _faster_ whether a new version is an improvement or not.
How you can help:
1) daily (preferably at the same time) run the class
"freenet/node/simulator/LongTermManySingleBlocksTest". It should be included in
the freenet jar I think. This will generate a CSV file with current and previous
fetch results and inserts.
2) You can guarantee that tampering with the fetch results is impossible by
removing the actual CHK keys. You can use sed to do this [1]. I prefer to
receive results which don't contain the actual full CHK keys.
3) Upload the resulting CSV file to Freenet or make it available at some
'regular' URL where I can pull it from. Nextgens (IRC) made his simple bash
script available to insert it automatically into Freenet [2]
4) Tell me the link or Freenet USK key such that it can be combined with other
samples. Please provide the time (GMT+0) at which you start each daily test (max 2).
5) 'Profit' by having your data included at:

(yes the layout sucks)
Please spread the word on FMS/Freetalk/Sone/Flip/... as you see fit.
Thanks in advance,
Thomas
