Tuna badly struggles on large files

[nicholasbailey]

I'm working a relatively large cProfile dump while analyzing startup of a django application. The profile file size is 9.4MB. Snakeviz is able to load this, though it can't visualize at a depth of more than 5 calls. Tuna just fails to load a file of this size. It looks like this is probably a result of eager-loading the entire profiling data set.

I get "Aww snap" in chrome for a 2.2 MB file, on a machine with 32 GB of RAM.
