I'm still catching up so somebody may have added to this, but adding recordlength=65535 with the direct=y will improve it even more.
I ran across an export that was taking 9 1/2 to 10 hours to complete (the resulting dmp file was about 7GB compressed). I added DIRECT=Y and it now takes 3 1/2 hours. My question is: What are the reasons that someone would choose not to use DIRECT=Y? This is an 8.1.5.0.0 database running on a Solaris box; I would hate to have just removed a work around for some 8.1.5.0.0 bug! I have found comments in some scripts here, but they all seem to be in my handwriting!!
