[GTER] Usuários Accel-ppp, contato para troca de experiências

[Marcelo Gondim]

Por falar nisso... faz tempo que não uso o Linux para roteamento com 
alto tráfego de banda e PPS (exemplo de 3Gbps e mais de 1mpps). Aquele 
problema que assombrava muita gente, o ksoftirqd, ele foi melhorado? 
Porque eu lembro que quando tive problemas sérios com ele, só consegui 
resolver mudando para BSD. Mas seria interessante saber se houve 
melhorias nessa parte.
