Hojla!
Pa poglejmo ali tega kdo ve :)
Po dolgem guglanju in brskanju sem ugotovil, da je moj AFP/netatalk server
počasen kot svinja zaradi "delayed ACK"[1]. Na strani Netatalk sem našel
rešitev za svoj problem [2], ampak žal je rešitev uporabna za nekaj deset
(mogoče 100 :) kernelov nazaj.
Najbližje pridejo navodila za RedHat [3], vendar v mojem kernelu 3.17.7
tega vraga ni :(
Ima kdo idejo, kako si ga pričaram v kernel. Po možnosti brez
patch-recompile-debug-debug...
Hvala in srečno,
Miha
