[OpenAFS] Extremely poor write performance.

>>>>>>>> Conclusion: No effect.

I concluded the same thing.  The load average on my client hit a record 
high 30+.  Rubino, I am the same situation you are, and relate completely 
to your posts.

Any suggestions for a memory cache size on a client with 256 megs of ram?  
I will play with this more tomorrow.
