Disc block size (was: Problem identified: WAPL/RAIDframe performance problems)

2012-12-02 Thread Edgar Fuß
Is that wrong, or am I missing something else? Well, I guess that you could end up with the third 512b-block failing and so your 4k chunk written halfway through. Whoever cares about that.

[Dennis, sorry for the off-list copy of a similar reply; my botch.] I believe every use of BPF by an application to send and receive protocol traffic is a signal that something is missing in the host's network implementation, [...] ...in general, I agree, but in the case of DHCP, I'm not so
