Hi,
you are not looking at the right cache. THe right cache is
red_client_shared_cache.h (shared among multiple monitors; doesn't
store images, only ids).
The cached you looked at is the cache of the canvas.
Cheers,
Yonit.

I suspect the image caching in the server is not the greatest:
1. Using latest Fedora 15 and QXL driver, I don't see any image being
cached - at all.
2. Using XP with latest QXL driver, I do see some caching activity, but
I suspect:
- the cache is limited to 2(!) items only (as IMAGE_CACHE_MAX_ITEMS is 2)
- even if we fix the above (so IMAGE_CACHE_MAX_ITEMS is
2*IMAGE_CACHE_HASH_SIZE for example) there will be, many times, slot
collisions. May or may not be such a big deal, depends how much we
really think we'll be caching.
- we are not caching that many images anyway. I expected with the above
change to have a lot more images cached. I suspect the driver does not
send many images for caching to the server for some reason.
All that I've done to gather the above is sprinkle some red_printf()'s
after reading the code:
