All Macs In-Depth Tests
Mac OS 8.6 vs Mac OS 9 A Benchmark Rumble!
The graphs below represent a Mac OS performance comparison between OS 8.6 and OS 9.0. The test machine was a "Rev B" iMac G3/233 with 96MB of installed RAM and virtual memory set to 97MB. Disk cache settings were left at the default setting with the exception of the MacBench tests which require a 512k cache for consistency. All tests were performed with all of the OS extensions on. For the "real world" tests below we set the scores relative to OS 8.6 which received a score of 100% Lower numbers and shorter bars are better.

For the network transfer tests a 10BaseT network was used. Both machines were running the OS being tested and were the only active machines on the network. For the OS 9 tests, we used both standard file sharing and the new file sharing via TCP/IP option.The "multi-file" test used the same 80MB folder from the tests above. For the 25MB "single file" test we used the ubiquitous Star Wars, Episode I trailer.



Below you will find MacBench 5.0 scores. In this case higher numbers and longer bars are better. Scores are relative to OS 9.0 which was set to 100%
