Faster X Display

[Fred @ Slate Industries]

Just thought I would share this.

I was having problems Whipping 20,000+

surface models around and asked for more Ram

Or something?

The I.T. guy increased my "Page file"?

No problems now

From what to what????

I've been looking into this myself for the video editing that I do at home.

i would like to know as well?

[Fred @ Slate Industries]

I'll ask, hang on.

[Randy Morton @ Clem Industrial]

Hanging on....

[jagg2499]

still hanging also

[Fred @ Slate Industries]

Its at 1.29Gig now I don't know what it was before.

When I see I.T. I'll ask.

Tony,

 

Your "page file" is also known as Virtual Memory.

 

As a basis for comparison, how much system RAM does your computer have?

 

To view your settings;

 

Right click on My Computer, Properties, Advanced Tab, Performance Settings, Advanced Tab, Change

 

Custom size:

 

Initial size (MB): XXXX (usually 1.5 x system RAM)

 

Maximum size (MB): XXXX (usually 3 x system RAM)

 

Having adequate room on the hard drive to allow the maximum size of the page file is a must. I realize this shouldn't be a problem with today's HDD capacities. It might also help if your disks are tidied and defragged before trying this.

 

I'm pretty sure that having a seperate drive just for the page file is the best way to set it up for those of you who are really interested in performance gains.

Now if I have my computer set with 2 partitions can I set both page file sizes 3 X in mb's what my ram is? or is it unnecessary to set my secondary drive considering it is not for programs just for storing data files?

[dwsz71]

concepttool,

 

Optimally, I believe you would want to set-up a completely separate disk, not a partition. I say this because read/writes by applications, back ground apps and the page file will cause bottle necks. Reading/Writing to disk (MB/s) is much slower than RAM (GB/s). So having a disk dedicated to the Page File should be more beneficial than a partition on the primary drive. Perhaps having a partition for the page file on a secondary storage drive would work just as well.

 

Sounds like a project for the weekend.

 

Page file info can be found here.

1/2 gig of ram (I have another 1/2 on order)

835mb of virtual memory.

what is the diference between a disc and a partition? I have my HDD split to C and D. C is set to 20gb this is where my OS and all my programs are kept D is the remainder 140 gbs and this is basically a storage closet only for files I have created

concepttool......

Basically they are the same thing. You have a Physical Hard Drive (160 Gb) partitioned into two separate Virtual Disk Drives,(C:=20 Gb, and D:=140 Gb) if I remember correctly.

[dwsz71]

concept/ocean,

 

They are and they are not. The easiest thing to overlook is throughput.

 

Try this:

 

When copying files between partitions the head is constantly moving reading (and being interrupted by the system), then writing ( and being interrupted by the system). Constantly back and forth.

 

When copying files between drives (separate hard drives) one drive reads, while the other writes.

 

There is supposed to be much less latency when copying between disks than copying between partitions of the same physical disk.

 

Make sense?

 

Maybe someone else can translate that dribble into something coherant...

[within a thou]

I understand what ya are saying there but how does that effect the way the graphics appear on mcam is it effected because the actual file is in D when the virtual memory is in C so it keeps having to jump to C to get what it needs?

[Fred @ Slate Industries]

It picked up the Speed of the Graffics for me

When I Dynamicly move my model around.

No more lagging.

[travis meyer]

this is what my virtual memory is set at and i got a gig ram. this works relly good.

Custom size:

Initial size (MB):2000

Maximum size (MB): 4096

[dwsz71]

concept,

 

Forget the D and C stuff. It's just more confusing. The file is resident in memory, be it system or virtual, as soon as it is opened. Read the article in the link above. It explains that even though your system may still have physical (system) memory, things are still being placed in virtual memory.

 

As far a why it helped Tony, I couldn't tell you exactly. It must have been a whopper of a file and maxed out all of his memory resources, making things take longer to refresh. He (and probably the IT guy) is the only one who's seen the before and after. I can honestly say that I have no idea how Mastercam takes advantage of system resources. I see alot of threads on the forum about what's stable, not what's fast.

 

From my personal experience a Quardo FX 500, GeForce 7800GTX, and Radeon 9700 Mobility all perform at the same level. But I don't work on 20,000+ surface files, either.

 

I was just trying to help those, who were eagerly waiting for his reply, get some information incase it sounded like something they might want to try for themselves. If his IT department is anything like mine, the forum folk could have been waiting a while.

thanks guys I did read the article but it misht as well be written in chinese
