Hello Ervin,
The in-memory cache lookup could be added back into
samba-4.1.6 by applying the attached patch,
if it could be compiled with Louis how-to steps,
perhaps got the chance to make U14.04 be stayed on samba-4.
Here is my test,
the test-bench is uploading 5000 files and each one is 1MB.
The attached patch could improve 15% at case B).
Case A) Original samba-4.1.6
will go through gete{uid, gid},
and takes 100 seconds to finish the uploading.
Case B) Original samba-4.1.6 with patch
will not go through gete{uid, gid},
and takes 85 seconds to finish the uploading.

Hi Jones, many thanks again four your help and your time. Thanks for the patch too - I'll check it up. On my Ubuntu, there is a Samba 4.1.6. I'll install the samba source package, and will try to apply the patch, then - I hope - the package will be compiled as well. I'll notify to you about the result. (First, I need to upgrade that server.)
