Whether you'll see any performance improvement is dependent on what the software does. Perhaps you will. There are some cases where I do in my own code. In general, though, most people don't. If you want to build this software as 64-bit and Debian does not provide 64-bit versions of those libraries, you'll have to build your own 64-bit copies by hand. Again, whether there's any performance improvement from doing that is dependent on the particular programs and libraries. sparc32 tells the program you give it that the system is 32-bit. It does this by changing the uname -m output. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
