(On the other hand, depending on how expensive your programmers are remember that fast computers with 64GiB RAM are no longer outrageously expensive, even as rented hosts.)
Actually, it isn't to avoid t buy PCs with a lto of RAM machines, but to save time when launching the application. I let you imagine how long it takes to load the data in RAM when I debug (even if I use then a light dataset of 5 GB).
I'd be surprised if the interprocess vector cost more than another pointer or two over the regular std::vector. They both need the extra space for capacity vs. size, pointer to start of memory, etc.
I didn't use vectors, but arrays based on pointers. I started a new thread about porting that with offset_ptr.
