I've been using the Proxy FSAL for the past two years and have had much
better results since moving to the V4.dev branch about a year ago,
particularly after Solomon Boulos' improvements to the Proxy FSAL.  I
don't claim to be using it exactly as you've described but I believe it
may be worth your while to try the V4.dev branch.

Thanks for the hints - I'll give it a shot - either see if packages are available or just compile it myself.
