This is write-through to the AFS cache from the Windows page cache; not write-through to the file server. In any case, it is a performance hit but is a necessary one. Otherwise, it is possible for the page cache to fill with data intended for AFS and it become impossible for the pages to be cleared in a timely fashion to make room for non-AFS data. The page cache is quite often many multiples in size of the AFS cache. The change was made in 1.7.12 not 1.7.11. Jeffrey Altman
