[DRBD-user] bonding more than two network cards still a bad idea?

Hi all,

I remember doing some research about bonding more than two network cards and 
having found that Linbit had shown that this does not really improve 
performance because of the TCP reordering. 

I was just wondering if this is still the case, provided more recent 
developments with new hardware and stuff.

I just saw bonnie++ hit more than 250 MB/sec while my bonded gigabit gives me 
about 160 MB/sec with 30% TCP header penalty, so looking into this is useful.

If not, I will be looking at 10Gb cards I guess ...

thx,


B.
