I will try that as soon as my spare production server (2x4core Xeon,
32GB RAM, 8 SAS Disk) is back to life.

I wasn't thinking about the very aggressive (strategy_always)
compression strategy for a default postgresql release.
Not everyone is IObound :)

But just as a default setting here at over-blog. (definitively IOBound
with large articles and comment).
Anyway, i will try and report different strategy here.

Thank you again for your feedback.
