Hello!
Origin 7.5SR6, Windows XP Pro
hardware: Pentium D 2*2,8GHz, 2GB Ram
I am mainly looking for people with similar experience and wonder if anybody has found a solution.
I am working with projects containing often more than hundred datasets with multiple columns, several MB of file size. I have that data organized in subfolders inside the project. Now when I export all subfolders, the summed size of the project parts is bigger than the project was before. If I start a new project and import all the parts, the project will be 20% bigger than the one I started with, simply by seperating and re-merging.
In that big (20MB) file, it takes more than two seconds to change into a subfolder and opening a graph.
Is all this a known problem, which is being worked on? Otherwise, one has clearly to advise against using Origin for big projects.
Greetings, Norman. |

Hi Norman,
Would you mind to share us your OPJ file and let's look into it?
You can upload your file to ftp://ftp.originlab.com/incoming/
Thanks
Fay

Dear Fay!
I just uploaded performance_and_size_problems_with_big_files.zip. Please delete it as soon as you have stored it locally, I do not want to have it world-readable forever.
Find my comments and an explanation int readme.txt.
Thanks so far, good luck, Norman. |

Since Fay will not be back until Monday, I have gotten that zip file and deleted it from our ftp.
I have created traker 12032 for this issue.
Thanks.
CP

Hi Norman,
Thanks for the projects and for the extensive explanations.
The bug that causes inordinate growth of file size will be fixed in 8.0 SR3 (to be released in a few days). After you load the project (such as project1.opj) once into Origin 8.0 SR3 and save it, the file size will go down substantially (likewise the time needed to load your projects).
Until Origin 8.0 SR3 is out, you can clean up your projects using Origin 7.5 by executing the following two commands in the Script Window:
del -v col(*;
del -v c:*;
(you can just copy and paste into the Script Window the above two lines, select them, and hit "Enter"). This will clean the project almost as well as when you load them into 8.0 SR3 and save. For example, the size of project1_emptied.opj goes down from 608KB to 21KB.
Some "loose" datasets (i.e. those that were not in any worksheet/matrix and hence could not be removed by removing worksheets/matrices) will still remain. For example, in project1_emptied.opj there are four such datasets (you can see them using the LabTalk command list s;):
1* Layout1_Ekorr025
2* Layout1A_Ekorr025
3* Layout1B_Ekorr025
4* Layout1C_Ekorr025
They seem to be small, though. If you wish, you can delete them one-by-one using del command thusly:
del Layout1_Ekorr025
Thanks.

Well, this is something that I experience, too. Additionally, if I try to change a graphs axes by double click on one of them, I see some funky black and white flashing and blinking for up to several minutes until the menu finally pops up... |
