OT - SSD & Autocad
Wife uses an I7 with 16Gb ram under Win7 Pro. New contract so wondering if putting in a SSD hard disk as primary would in the real world speed up Autocad (latest version) which even with pc she uses seems slow somtimes to her. I know it'd speed up the system overall but am more interested in would it actually speed up Autocad while using it and not just load times etc. |

I know it'd speed up the system overall but am more interested in would it actually speed up Autocad while using it and not just load times etc. When you use the Performance plugin and watch disk write bytes/sec, read bytes/sec, writes per sec, reads per sec, what do you see ? That's something I do to quantify disk activity. Modern disks can carry out an amazing number of I/O per second, as the cache RAM on the disk drive controller actually gets used for its intended purpose now. In fact, for some OSes, it's the OS itself which begins to saturate (maybe at more than 10,000 I/O per sec level). It's possible with some storage devices, that the weakest link ends up being the OS (I noticed this on my RAMDisk). A second thing you can try, is sysinternals.com Process Monitor, start the trace with no filter events. Carry out a CAD session, and watch all the activity. The log will have a record of file operations, the size of each read and write. You can set Process Monitor to record events to disk, rather than run it RAM backed, for really big traces. You might not need all that info, but if you absolutely must see the I/O portion, that can give some ideas. You can also use your Task Manager, to study CPU usage. And see if it's being a pig on the CPU front. ******* Autocad is also likely to place an OpenGL load on the graphics card. But I don't have any magic study tools for that. Some desktop cards, the silicon has plenty of horsepower, but the driver provided by ATI/NVidia is "neutered" on purpose. To make you want to go out and buy some overpriced FireGL card. If I run SpecViewPerf on my current video card, it is dog slow for that. Whereas a game doing more detail than that, works just fine. My SpecViewPerf runs might be running at 1 FPS. Whereas a game with a decent number of polygons is 30FPS. Generally, you want to find an Autocad forum, to get the scoop on hardware speedup. It's too much work to reverse engineer that stuff all by yourself, when occasionally at least one CAD user has enough clues to figure out what it needs. And what the graphics card is doing, is the part I'd have trouble quantifying. According to this, older versions of Autocad used Direct3D, whereas the version mentioned in this article uses OpenGL. And that allows the FireGL/Quadro scam to be pulled ("we only give you a good driver, if you buy our unnecessarily expensive video card"). If you use a regular desktop video card, the driver for it is not as good for OpenGL, on purpose. http://www.nvidia.com/object/autocad...f_drivers.html At one time, there were hacks to convert a desktop card, into one of the other flavors. And in that era, people would then be in a position to do head to head comparisons of what the driver component was doing to them. I doubt any modern card leaves that signal just sitting there, to be tweaked with a soldering iron. Paul |

Well, check the way Paul described first - though I must admit wondering if just looking at the HD access light (perhaps with a magnifying glass, and in the dark if possible) when she's doing something she feels is slow might answer the question! Additionally, if doubling the RAM is in the budget, that might be a good idea too. Again, first, I'd check with Task Manager (while doing something ...) to see if you're getting anywhere near the 16G; if not, then upping it probably won't help. IMO anyway. -- J. P. Gilliver.

She runs newest Acad with regular updates (company/contract insists) and what little I've noticed is she complains about redraw times. I assume there's a fair amount of paging going on doing that given drawings are well over the 16 Gb ram she has. Therefore SSD would help likely very noticably with that. Are you sure you have the 16 Gb size for the working file right? That's a huge file for Cad. Hell, that's a huge file for anything. If it really is 16 Gig, I think you can expect wait time while it redraws. Not knowing what type of work she is doing, the one thing I would suggest to her is to try and turn off any layers that aren't necessary, and try to break it down if possible. I work with files a fraction of that size and it gives my I7 a workout. sticks |
