Hi Rajesh.
patchadd -t will result in dependency checking being done by script.
patchadd (without -t) results in dependency checking being done in C,
which in theory should be faster.
However, the person who made the changes says he is not convinced that
-t slows things down (or, put a different way, that puting the checking
in pdo speeds things up). (The changes were done anyway, as they were
made for other reasons as well.)
Performance changes have not been formally documented.
Thanks,
Jack
