Quick update guys ...

I've just checked performance running 4.1.8 Beta and this behaves exactly like 4.1.7 ... good news ...

- Under 4.1.8-T9 with AFP and Bonjour disabled, I measure read speeds of 19.9 MB/s
- Under 4.1.8-T9 with AFP and Bonjour enabled, I measure read speeds of 19.9 MB/s

Write speeds are identical to 4.1.7 too at around 13MB/s. No performance drop like that seen with 4.1.8 Release.

Looks like I'll be running with the beta software for a while but that's far from ideal ... a temporary solution at best. With this (limited) testing it seems like performance problems were introduced between the 4.1.8 Beta and its release, affecting devices with AFP/Bonjour enabled.

As before, I'd be grateful if anyone could confirm this themselves (or contrast it with different behaviour) independently.

Thanks,

Justin

PS. Thanks Dfiler .... your own switch back to 4.1.8-T9 gave me good confidence this would be OK
