The specific case I had was serializing an array containing a whole bunch of arrays representing the data from tables in a database. I don't recall how many rows there were, but the serialized data was around 5 MB. This was on windows, and feels like realloc doing over-time, so a fix could be something as simple as tweaking the smart_str chunking code; start with a fair initial size and perhaps having it double the size on each realloc. Of course, a competition for the fastest serializer would be nice too :) --Wez.
