Thanks to some helpful people on the list, we were able to figure out why in our test environment, framebuffer writes were slow. We changed the way the mapping worked to enable write combining, and it now gets very good throughput. But we've since noticed that READS only get about 4 megabytes/sec. Does anyone have any insight into this? Surely, there must be some way to enable an optimization to reads as well, no?
