+qemu-monitor screendump very slow
+
+qemu-monitor screendump often using 10-20% cpu usage of one core to take a small capture.
+
+Most of the CPU usage seems to come from libpixman. There were many reports of libpixman becoming 8 times slower in newer releases.

+I tried taking a look on how to fix this, but it seems pixmap is deeply enrooted inside the monitor.  I wanted to try to simply take whats on the display and memcpy it into .ppm format manually creating the file header, but I cant figure out where the raw display buffer/image starts.
+
+For example this is DisplaySurface:
+
+struct DisplaySurface {
+    pixman_format_code_t format;
+    pixman_image_t *image;
+    uint8_t flags;
+#ifdef CONFIG_OPENGL
+    GLenum glformat;
+    GLenum gltype;
+    GLuint texture;
+#endif
+};
+
+Which as you can see already has the pixman_image_t. Maybe I should just work with that pixman_image_t?
+
+The most effective solution IMO seems to just memcpy from the display into a premade header for a .ppm or .bmp file assuming 24 or 32 bpp. No need for libpixman.
