Two more patches left to apply, one is the code refactor without
functional changes and the other is passing file/dir mode to
create/mkdir without separate calls to get_attr.
Will integrate these two next week.

Ram.

Thought I'd give a status update.
I've integrated the following patches (with some minor
changes/additions) after testing them out a bit.
vbox.panic-params.patch
vbox.stat-ttl.patch
vbox.dir-seek.patch
I'm giving more priority to the patches that address bugs. Patches
that improve performance will also be integrated but after the
bug-fix ones are done.
Thanks! I completely understand. As you've probably already figured
out, the above plus the vbox.dir-stat.patch and vbox.alloc-size.patch
are basically bug fixes; the vbox.pre-symlink-refactor.patch and
vbox.symlink.patch are an enhancement (i.e. symlink support); the rest
of the patches are purely performance and related refactoring.
Yes, I had an overview of them all. I also added some other minor fixes
like using strncpy() so we don't write past the d_name size and such.
I've also integrated the vbox.dir-stat.patch. Will continue with the
other patches in the coming days. Thanks & Regards,
Ram.
Cheers,
Ronald

Attached are some patches to improve the performance of
shared-folders
in Solaris guests. Together they speed up things between 2 to 4
times:
operations like untarring and deleting whole directory tree are
typically 2 to 2.5 times faster, and when running builds that
include
things like building Solaris packages I see a speedup of 3 to
almost 4.
The bulk of the speedup comes from the second (file open) patch.
These patches assume my previously sent patches have been applied.

Thank you very much for this code contribution! We will revise it
a bit
later as our colleague which maintains this code is currently not
available.
I don't want to appear pushy, but since I've seen that some work has
been done in recent weeks on the Solaris shared-folders code, I'm
wondering if you might have time to review the patches. I rebased them
onto svn rev 39192 (and updated to VB 4.1.6) and they appear to still
work fine on Solaris 10u8 (after disabling the mmap support - see
https://www.virtualbox.org/ticket/9856).
For your convenience I've attached the rebased patches (in the order
they should be applied), though all in one email instead of spread
over 4 separate emails like last Jan.
Argh! I just realized that the symlink deletion issue was fixed a
while ago, so the hack in vbox.symlink.patch is not necessary anymore
(yay!). Since updating this patch causes some subsequent patches to
not apply cleanly anymore, I'm just re-sending the full list of
patches (i.e. please ignore those I sent yesterday).
Cheers,
Ronald
