Hi Zach, Setting affinity should help, I don't think OSG-1.0 had support for affinity, and OpenThreads certainly didn't have for Windows till very recently.
When setting affinity there are also question makes about setting the affinity of the main thread and setting the affinity before starting the thread vs after. Different platforms appear to have different rules about when you can and can't set affinity. Setting affinity before starting the thread will be the most full proof solution but I'm not familiar with the Windows side so can't say for sure. FYI, The new osgViewer library does attempt to set the viewer and database pager affinity. Robert. On 3/3/07, Zach Deedler <[EMAIL PROTECTED]> wrote:
Hello osg-pagers, I have a paged database that I'm trying to improve performance with. OS: Windows XP CPU: dual-core Pentium D Video: GeForce 7800 GTX OSG: 1.0 The biggest problem I'm seeing is mult-frame hitching. I haven't narrowed down the source of the problem. Anybody have any ideas? I'm interested to know in others experiences with paging, and how to optimize it. Do you think setting the pager to one CPU, and the viewer to the other CPU would help? Currently, I do nothing with affinity. Thanks a lot!
