Driver instrumentation overhead



I’'m currently trying to profile my GLES application on a PowerVR6 machine with a 1.7 driver. I measured the performance of glDrawArrays and measured about 800 small calls to malloc per call. Is that normal? Is it part of the driver instrumentation / logging?




can you please provide more details about your machine?
what is the exact device? what GPU exactly?
what is the driver’s exact version? eg. 1.7@???
what operating system do you use?

driver behaviour depends on what you are trying to do. Can you please provide details on what you are doing in OpenGL?
