Did it mention that it was in the context of csv or an excel file? I only say that because, as someone who is painfully aware of the limitations and problems of those formats, I'm similarly aware of getting "that web-guy" on a project who proclaims "lets put things in a modern xlm format!", and lo and behold the process is now an order of magnitude slower and the xml format an order of magnitude larger than the simple delimited tabular format or stream. I'm also painfully aware of the old systems (and how old health systems are) with fixed sized buffers and processes, so I can see how this would happen in the context of a lot of computing. Edit: i see later on someone is mentioning that twitter suggests it had to do with excel file size limitations...
