This sounds a bit confused. Are you able to describe your concern?
You said star doesn't run as fast on Linux as Solaris, you can probably
fix that problem by using O_DIRECT, so the writes and reads don't
compete for the same buffer memory.
And I already mentioned that it is higly improbable that O_DIRECT will
speed up on Linux. A better buffer cache (this means improving Linux) helps
much more than avoiding it.
How would a buffer cache improve the situation for star? I may have
missed the beginning of the discussion, but caching
write-once-then-forget data seems pointless.
