This operation is considerably faster than retrieving it from the hard drive – in computer terms, it's days versus weeks. It's fairly likely that the data will be needed again soon, and if so, the memory compressor decompresses it and puts it back in main memory. When the OS runs low on RAM and swaps something out to disk, the memory compressor intercepts this, compresses the contents using a fast algorithm, but keeps it in RAM. Memory compression introduces a layer in between these: it partitions off a block of system memory for compression.

OSes that support virtual memory have a two-way split, between real physical RAM and virtual memory in a file on disk. The most common ones will be SC4 Terraformer (you can download it at SC4Devotion, do a Google. Memory compression works by introducing a second level of swapping to the OS. Even better, there are lots of areas of the world that have been converted to game regions (and a user who will take your requests for new ones), but you'll need some Graphical Editing tools to be able to put them into the game. Doubling your system's RAM sounded like a great deal in 1994, when a 4MB SIMM would cost $170 – £230 today. This crazy-sounding idea first appeared with Connectix's RAMdoubler in 1994, an add-on for Mac OS 7.6 – a slightly easier proposition as classic Mac OS didn't have true preemptive multitasking. What SoftRAM 95 claimed to do was software memory compression – on-the-fly compressing data in RAM so that your OS has more fast storage available than without the software. Yes, in the 16 city regions the cities can trade down the river/rail with a few more, but sims only travel by rail/road so the bulk of inter-city interaction is in the 4-city clusters. It’s a step-by-step guide on creating a series cities that work in tandem with each other to create a working region. Less than that and you're sacrificing features. SimCity 4 Region Strategy Guide This is the Region Strategy Guide, authored by Maxis and previously available on the official SimCity 4 website. There are few lessons about modern software in there as well. A 4 city region is a 'city' in the SC13 context. One of the most consistently interesting and entertaining Microsoft blogs, Raymond Chen's Old New Thing, recently covered the dissection of a best-selling bit of software for Windows 95 – SoftRAM 95.
