Being able to run 3000 simultaneous processes (32-bit) instead of only 2400 processes (64-bit) can be an advantage that out-weighs the minor losses to each individual process. RAM is cheap [and a capital cost], racks are expensive [and an operating cost for power, cooling, rent.] -- -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
