ok thnx David for your reply, I will tell the customer to check the file, have you got an tips to

optimise a Big file (no not CTRL + A then Delete everything :-) hehe just kidding) I’m just not

familiar how stardraw Works.

Is there an other option for increasing the performance, does a better video card, processor or memory increase anything?



thnx

Jordi

If the size of the file is greater than 10MB, then I'm not surprised that it can take up to a minute to load up. I would look at why the file is so large. Stardraw files are very, very efficient and are compressed and in AutoCAD this file would be nearly 100MB in size.

As for using 50% of the CPU, this is because you have a Dual Core 2 Processor. This effectively has 2 processors in it. The loading of a file in Stardraw is done in one thread and will take one of those processors. The 50% CPU usage you are seeing is the overall CPU usage, including the other processor.

Hi,
 
I’ve got a question my company recently sell a Hp XW4400 Professional Workstation to a client that uses your application Stardraw Lighting 2D 2007. They bought the new PC because they found the old pc was al little bit slow it was slow when they open a drawing,  when they create a new layer and when they disable and enable a layer. now with the new pc they have the same problems. The drawings (+/- 10 MB file) take about 1 minute to open. First I thought it was a network speed problem but when I copied the file to the local hard drive it didn’t get faster. I disabled the virus scanner and some other tools but no go. When I look in the task list (when I open the drawing) and look at the performance of the CPU I see that it doesn’t come above the 50% !! stardraw.exe uses 50 % of de CPU and there is still 50 % CPU free why doesn’t is take more cpu ?
Can you help me?
Btw, Does it help if the video card has 1 GHz of memory? does stardraw uses the video memory often?

the System specs are:
 
HP XW4400
2GB memory
Intel Duo Core 2 Ghz
Windows XP Sp2
ATI  X1950 -  256 DDR3 memory
 
old system specs:
PIV 2,8 GHz
1 GB memory
Nvidia 512 G7200 LE
 
thanks,
 
grtz
