When running IOzone to carry out an 8GB write test with 64Kb blocks, the Lenovo ThinkPad T61 regressed hard between Ubuntu 10.04.1 LTS and Ubuntu 10.10 RC. With the other test system, however, there is a nice performance improvement in the disk's write speed. The standard deviation on all of these test runs for both systems was less than 2% with each being run three times per OS release, which does make the IOzone write test results rather interesting for Ubuntu 10.10.
As another disk benchmark, we ran the PostMark test. The Lenovo ThinkPad T61 had near identical results across the past three Ubuntu Linux releases, but with the Intel Core i3 system there was a large regression between Ubuntu 10.04.1 LTS and Ubuntu 10.10.
Lastly, when using the network-loopback test profile for a kernel networking stack benchmark, the performance on both systems does improve significantly when upgrading from Ubuntu 10.04.1 LTS to Ubuntu 10.10 RC. These improvements can be attributed to some networking improvements made upstream in the Linux 2.6.35 kernel.
For the most part the Ubuntu 10.10 "Maverick Meerkat" performance is not hugely different from that of recent Ubuntu Linux releases. However, there are a few areas worth noting, such as with the network performance improving but the disk / EXT4 performance again regressing in a couple areas. The graphics results also continue to be interesting as the open-source drivers mature. Stay tuned for more Ubuntu 10.10 benchmarks across a greater spectrum of hardware.
