What do you think, Loading of Image takes time or pushing them into GL textures ? We are not very sure about the h/w but it might be something like OMAP3430. I am trying to load around 15 png images ( 320*240). >> - Have any one done performance analysis of clutter? >we do profile our code whenever is possible, and we try very hard to >improve the basic Clutter performances - but most of the performances >are a matter of user code (how many textures, how many animations, how >much text, which GPU), not library code. Ok , I also guessed the same. Actually my questions were wrt 1: Whats the Cache'ing mechanism. How does it put some of those textures in Cache memory. 2: Whats the memory requirement wrt RAM and Cache ? 3: Just to make sure we are not goofing up anything in our application code what tool do you suggest me to use to profile and also to check memory leaks in my application ? >> - How Fast it will behave if we'll use pango. Which is a very big lib. >I honestly fail to see the connection between Pango and textures. or >with the size of the library (which is not very large and it is shared >among all processes using it). My question is, Because Clutter uses Pango and Pango internally loads specific fonts , My observation is it takes good amount of time to Load and Render the Texts ? 1: Do you think there exists a "light-weight Pango" what I can use with clutter for better performance. (Pls blame my limited knowledge on Pango for asking this)? 2: Let me know if at all there is any possibility for clutter to use anything other than Pango for Text effects? 3: Basically 'what I am looking for', is a better performance on embedded device. You can suggest me with any other idea if you have. 4: Can we hardware accelerate Pango (Just a thought)? ciao, Emmanuele. -- Emmanuele Bassi, OpenedHand Ltd.
