SSI-1.9 CFS to support read ahead at server.
Logged In: YES
Done for CFS server.
This was disabled by Zafman or John or someone, but my finding is no obvious performance hit when enabled - rather an increase in performance.
Apparently 1.9.3 still has read ahead caching disabled, but 1.9.3 did fix read ahead thrashing.
Now testing code that enables the read ahead cache by initializing the amount of caching to that determined by CFS and/or PFS.
