Hi, buddies: We confirmed that the graphics adapter card is most influencing for the performance of clutter.
The glxgears FPS info here for two kind of graphics adapter: For NVIDIA GeForce GT440 is 60FPS, so load image texture will be very slow For AMD Radeon HD 6600 is 1700FPS Thanks for reading this. does anyone could tell us is this a problem of clutter or VirtualBox? Any tips would be thankful.

This func will cost more than 4s to load one image if already loaded many images before。 Then it will return to normal for loading others. It seems like the memory buffer is not enough for loading so many images, system need to allocate another buffer to load all the images. But when one of my colleague run this app, the issue doesn’t happen. Our environment is almost the same except Windows OS and PC hardware. My PC environment: Virtual Box 4.1.4 Ubuntu 11.10 Clutter 1.8.0 / Cogl 1.8.0 Windows XP Intel E8400 3.00G/GeForce GT 440 My Colleague PC environment: Virtual Box 4.1.4 Ubuntu 11.10 Clutter 1.8.0 / Cogl 1.8.0 Windows 7 Intel i5-2500 3.30G/Radeon HD 6600 Best regards / Mit freundlichen Grüßen BeQIK Chen Qing 陈 卿 CM/ESW2-CN Tel. +86 512 6767 5572 Fax +86 512 6762 1200
