Pomale DRBD a rozpadani se spojeni

Zdravim,
mam dva stroje (NodeA, NodeB), ktere jsou primo (FTP 50cm) propojeny
3x1Gbps LAN, spojene BONDem (viz "NodeX_interfaces"). Na kazdem jsou v
RAID5 4HDD. Tyto dva stroje synchronizuji data pomoci DRBD (viz.
"NodeA&NodeB_drbd_vm.res").
Aktualne:
kernel: 3.13.3 (a i mnoho predchozich)
drbd_kernel: 8.4.3
drbd8-utils: 8.4.4
Testovano jak s IPv4, tak i IPv6.
Problemy:
1) ackoliv RAID (md2) dokaze zapis/cteni pres 200MB/s (mereno
dd_rescue), tak DRBD mi to degraduje na cca 30-50MB/s (mereno dd_rescue)
a datovy tok na BONDu je neco kolem 300Mbps (mereno iftop).
Nekde jsem zahledl informaci, ze DRBD neumi vyuzit BONDu, ale proc
neudela vetsi sitovy provoz, alespon to co zvladne jedna LAN karta?
2) Pri vetsim zatizeni DRBD (kopiruje se vice dat z vice mist, ...) se
rozpadne spojeni, viz "NodeX_DRBD.log". Toto se mi deje jen na jednom
"Clusteru". Jiny, ktery ma stejnou konfiguraci ma jen problem pomalosti,
ale nerozpada se spojeni.
Oboje testovano i bez BONDu, jen na LAN...
Mate-li nekdo napad co stim, velmi rad ho vyzkousim. Uz me dochazi fantazie.

S pozdravem
