Ok heres a dumb IT Question for you....

Why is it that even though I have a mega machine with 24 Proccessing cores (4x Xeon X5650 Hex Core CPU's), 24GB of RAM, Twin SLi'd Nvidia Quadro 4000 Graphics Cards with 2GB DDR5 each - My Render times are so fecking slow even if I pass the Render information through to the CUDA Cores on the GPU's and use the CPU to process the Light Pass calcs in other words, I am using all 24 cores to calculate lighting information, the GPU Processors to render the final image and the CUDA Cores to process the shading it takes an age to render anything...???

(I am a design Engineer who specialises in 3D Concept modelling, Mechanical Design and 3D animation - hence the hardcore machine)

Assuming you are rendering locally, what hard disk are you using? SSD v3 would be first choice, but they are pricey. 60GB are cheap enough, but over 200GB and you'll pay. Second choice would be SAS. Last choice would be IDE/SATA which is what I bet are in there.

One of my staff once built a production file server for a dept out of SATA hard disks (it was an old backup storage server) and to say it was crap was an understatement. Our latest disk arrays are all solid state and our last few hundred desktops were all solid state and the performance difference (everything else being equal) is fantastic!

I can ask our renderers for other ideas???

Unless you have a lot of well compacted hardcore under it 6" maybe better. Standard mix would be 1 cement, 2 sharp sand, 3 aggregate. But do a search and decide for yourself.

Don't feel too smug, if your 4.6 was doing the same cycle you would be in single figures. Consumption depends on duty cycles and the topography of where you live.

Back and forth to work I have some hills and rarely get it over 20mph, the last month of consumption has averaged 17mpg.
I can hit 22mpg on a motorway and sustain it on a 200 mile drive each way to Kent including some major hills taken at 65-70mph.

Having driven 2.5 4 cyl Porsche for so long I all I am saying is that think the 4.6 is pretty good and not much worse than the disel. :)
 
Had in on a diagnostics. No problems. Had the VCU checked, its fine. Currently running at 18-19mpg on average - mainly short journeys.

Where are the obvious places to look to see if the car has been chipped in the past? There is a yellow relay that is located near the battery and doesn't look in keeping (partly because it's yellow), so I'm wondering if its been doctored in the past. But the Landrover specialists in Speke (Liverpool) gave it a clean bill of health and said it was all fine.

I've just done my first week on 100% biodiesel too (purchased, not home made) and it's running fine.

Cheers,

Nick

Short journeys in traffic around town at 30 mph or less that is about as much as you will get. Might get a bit more if you use cruise control as much as possible. Getting the injectors serviced may give a little improvement.

Could be some sort of hot start bodge that is causing it to run on cold settings all the time:eek:
 
Official figure for a new vehicle urban cycle is 20 mpg. If you are doing nothing but short journeys around town. 18 to 19 is all you will get. It depends on traffic and speed, stop start will drink fuel. Depends on the topography of your area, if you live in the country with little stop start traffic and you can drive at 40 to 50 mph or 50 plus most of the time you will easily get 25 mpg. If you are looking for 25 mpg plus driving short journeys around town in traffic you are in a dream world.

See told all you boys before go petrol V8 and have no mileage worries - you know its going to be bad so dont bother looking:D:D:D

I hate to think what a V8 petrol would be doing on my driving cycle. A total waste of space probably. I had the choice of several slightly newer V8s for the same price as the diesel, but when you know what's what it has to be a diesel every time. V8 the mans choice. Diesel the intelligent mans choice. :p:p:p
