Posted a way longer post in the REDCINE-X subforum, but I thought it might be better suited here, so I've just lifted the relevant bits, and also highlighted some questions I hope someone can assist me with. You can read the other thread here:

Boot ROM Version: MBP61.0057.B0C
SMC Version (system): 1.58f16
Both systems are running the latest updated versions of Mac OS X 6.5
Pro AVIO RAID, mirrored RAID set, connected via two eSATA cables (3Tb storage space, for transcoding)
8 x G-Tech 2Tb drives, for 3 x backup of R3D source material and editing Prores proxies on FCP system (still speculating on this we may need more)
Now, the question:
I wanna have the transcode work as efficiently as possible - so I require a good speed/safety ratio. The following questions all relate to this:
1) Will I see a performance boost running REDCINE-X build 348 (64bit) with Mac OS X 6.5 in 64bit mode? How is this different from running build 348 (64bit) 6.5 in 32bit mode? (Have read all kinds of reports on this, but wanna get some more opinions).
2) In which other ways can I tweak my system to optimize transcoding times? Clearing REDCINE-X's cache? Clearing the system's overall cache? Can anyone recommend any apps to assist with this, otherwise advise how to do it in the terminal?
3) In the event that we need to move locations, and use the MacBook Pro to transcode, will it be safe to transcode from the laptop's internal HDD to an external G-Tech 2Tb drive (via FW800)? Or should I daisy chain a Rugged Lacie (we'll get R3D source material from DIT on these drives) to the G-Tech? Which will be fastest/safest?
4) Since we're transcoding to Prores proxies with 1/2 Premium debayer, many shots often look soft or out of focus, while they're actually IN focus when you look at the R3D source material... I tried using Lanczos (sharper) vs. Mitchell (smoother) for my last transcode, but didn't see a marked improvement, and my transcode took just under 4 hours (and resulted in bigger file sizes) while my earlier transcodes (using Mitchell) were just under 3 hours with smaller filesizes... Any suggestions here?
5) Is it faster to (a) transcode from the RAID onto the RAID, (b) from the RAID onto the internal drives (SATA) or (c) from the RAID onto the external G-Tech drive (via eSATA)?
6) Does REDLine actually, REALLY make a difference in terms of speed? Does it hamper reliability?
