Ok - but when I try it on my servers (with the check of the tool removed) - it
seems quite impotent unless mod_deflate is in the wire.
And it seems a bit more potent when there is other 'keep in the air' modules
around.
So I guess mod_deflate is right now the largest 'plug' we have in the server
which can cause this backup ?
Or is that totally wrong. Happy to stand correctede !
