Zoomify Performance

I've been looking at the performance of the zif image module with respect to files pushing the limits of the TIF file format. Yep 3-4 gigabytes. In Zoomify terms around 160 levels. To do this I took some data from the Hubble space Telescope as composited and provided by NASA and first squared it then scaled it up by around 2x to about 40,000 x 40,000 pixels. I also created a set of data at 45,000 x 45,000 pixels but these wont load up. Not on the web and not locally either. It's funny. Well really not so much even with my i8-10850K and 64 gig memory and 760 EVO SSD'd my local system is slow to handle these images. Drupal does not handle large images too well at all either.


I have been experiencing some glitches with the system and I am going to try and quantify it. There are a lot of options. Local response vs Web Response. 4 different viewer codes and to tile schemes – JPG/PNG. So It's a lot to consider.


For timing I am gouing to use OBS and record snippets of the responses. I will use 60 fps frame Rates to try and Gage the duration of the glitches. At 60 fps I can time with a resolution of 1/60 sec. I,n hoping to sound frames to define the duration. I will use Avoidance Resolve for this purpose.
