The problem is similar to: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=117691 With /home/users/ being an NFS share: # time dd if=/dev/zero of=/home/users/tmp/testfile_wr bs=16k count=16384 16384+0 enregistrements lus. 16384+0 enregistrements ecrits. real 2m0.944s user 0m0.010s sys 0m0.660s # time dd if=/home/users/tmp/testfile_rd of=/dev/null bs=16k 16384+0 enregistrements lus. 16384+0 enregistrements ecrits. real 0m26.131s user 0m0.020s sys 0m0.300s Using another network card (Realtek 8139) shows decent outbound speed (around 36 seconds with the 8139 card). The machine is on a 10/100 network, with the cards set at 100Mbps. This is with kernel 2.4.21-9.EL and 2.4.21-9.0.1.EL
Created attachment 99232 [details] patch for TX IRQ handling Patch provided by the customer, Olivier Lepape <ol>

Also, the customer's patch is is very similar to what is in current upstream 2.4.
