Hi all!!
Please, could you tell me some possible reasons why CATIAv5 can works very Slow?? I am working good but suddenly CATIAv5 starts to work very slow, for example, when I try to remove something, to load a CATProduct, insert a line, so on....
I must kill the CATIAv5 proccess and start again. The problem is that I have this trouble very often and I can't work properly.
I have tried to remove the user CATSettings but I still have the same problem.
Do you have any ideas????
Very best regards |

GELETERE ,
It would be great if you could furnish us with more information.
Such as:
- What type of PC are you using (Windows 32 bit, Windows 64 bit, Unix, etc.)
- What type of OS are you using (Vista, XP,etc.)
- PC processor speed
- amount of RAM
- Graphics card RAM
- Catia Release and Service Pack
- Does this happen while working at the CATProduct level, or only while in a CATPart?
Help us out, so that we may help you.

The first thing I would check is the auto-save option. I recommend disabling it to improve performance. Tools->Options->General->General->Data Save->No Automatic Backup.
I have also seen some parts/products with links to Excel design tables which caused enormous performance problems. I could not isolate the exact problem, unfortunately. In such cases, I either removed the design table, or recreated the part with a new design table. Sorry that's not very helpful info.
Thanks,
Tomm |

Do you reboot your machine every now and than?
Look at the processes that are running on your machine and find what is eating your performance.
What did you do between normal behaviour and the slowing down?
Maybe resetting the priority of Catia to a higher level may help.

Thank you very much Frank. The machine is a machine of my company. I'm going to investigate if the machine reboots every nights (maybe not...). Then I will study the processes of it and check if there is a problem with the performance. I also will change the priority of Catia process...
About what I have done before the slowing down, I will need to investigate asking the user that has that machine...
when I finish my trials I will let you know.
Thanks a lot for your quick answers |

| When you pull up your Task Manager, what is the Memory Consumption of the CNEXT.exe process? You may be running out of memory. |

most likely to be a hardware or driver problem... i've had the best of machines grind to a halt due to something as simple as a dated graphics driver
Win2K is unsupported from R18 so upgrade with this in mind |

Hi all,
Finally I know that the machine reboots every nights. I have tried to increase the priority of the CNEXT process to a HIGH level but it doesn't matter. Is very very strange because the user is working without problems for example opening and closing CATProducts and loading its contents.
Suddenly, the CATProduct starts to load very very slow... fro example, if everything is ok, the user needs 10 seconds to load the CATProduct but when this problem starts the CATProducts needs about 30 minutes in load everything. The difference I see is that when the machine works fine, the models load at a very high speed (reading the cache cgrs) but when the machine works wrong, it takes about 10 seconds for each cgr (cgr of 10Kb!!!).
And when I kill the CNEXT process and open CATIA again everything works ok again... I don't understand. When I kill the CNEXT process the memory CATIA is using use to be about 600 or 700 Mb (it must work fine because the RAM is less than 1500).

Looks like we still need more information. Once the computer goes into this 'slow' mode, is it using 100% (or 50% for dual core, or 25% for quad core) all the time? If it is, that's one thing, if not, when DOES it max out?
Still, offhand I've never heard of anything that would explain the problems you're experiencing. We're slowly ruling out possibilities, such as virus scan activating, auto-save, out of memory, rare-restarts, etc though... Definitely sounds like it could be a hardware/driver issue. Make sure you have up-to-date graphics card drivers.
Wait, one more thing. Check your windows swap file limits. CATIA uses equal amounts of RAM and virtual swap from your HD. If for some reason your windows swap is limited to 768MB, I can see it behaving exactly as you are experiencing... |

| We have problems with some laptops that, at some stage are very slow with CATIA. The system guys cant find the cause, so we reinstall the "whole" PC (OS etc) to exclude any other rogue software that maybe causing it. That works and CATIA works fine. But we don't know where to look to find the problem without our drastic approach. |

Hi friends,
Thank you very much for your answers. They are all very much appreciated. I have reinstalled the PC that has this problem and I have still the same problem. I have discovered that the problem is not a hardware problem. The user that has this trouble also has it when he works in another machine.
I am sure that the problem is a problem of this user. I have also discover that he works good until the CNEXT process has a Memory Usage of 500Mb or higher. When this process is in 200 or 300Mb everything works fine but, when he starts to load some products and this value is increased until 500Mb the machine starts to work very very very slow... every actions you try to do are slow when CNEXT has 500 or higher.
Do you know is the user profile is wrong? Maybe in the registry? In somewhere there should have a bad configuration in the user profile that don't aloow the user to work with more than 500Mb of RAM, because the machina has 2Gb Ram and WINDOWS 2000... Catia should work slow when CNEXT has 1500Mb not 500Mb...
We are near of the final solution!!!! |

I'm not an expert by any means and I know this is way out there and oversimplified. If it's just that one user I would delete their CATSettings, restart CATIA and rebuild from scratch. I've had CATSettings do weird things, though not what you mentioned, and had to do that before. |

Hi Wichard,
The first thing I have done is remove the user CATSettings but the problem is still there.
Thanks for your answer

From everything I've read here I think it's very clear that you're running into a memory constraint. 2GB is really very little memory to have on a machine that runs CATIA. I'm not sure what the memory consumption is for Win2K any longer, I expect it's less than XP, but I do know there's a point where Windows will not allocate any more system memory to an application and switch to swap disk in order to preserve system stability. My guess is that this is why your user is experiencing this slowness.
We had a similar situation where our production machines (running Server 2003 32bit) would fail to load larger assemblies. I could watch CATIA get up to about 1.7 GB of memory consumption and then it would simply quit. At the time we only had 3 GB on these machines with nothing but the OS, typical OS launched apps, and CATIA running. So it was fairly obvious that memory was the likely culprit. We bumped the machine up to 4GB of RAM and everything is fine. CATIA now has enough available memory to load our larger models and things run much more smoothly. |

What are your Linked Document Localization settings? Are these parts being loaded locally or from a network location?
