IOzone Performance Exploration, Part 2

Filed under
Linux

In our previous Part 1 of this series we looked at the IOzone performance for ext3, ext4, and reiser4 using larger size record lengths (1MB, 4MB, 8MB, 16MB). The results are interesting because they unexpectedly showed some trends in performance that are independent of the file system. These observations are important if you take the results from a single record size run of IOzone and apply it to other record sizes (which you shouldn’t do).

In this article the number of file systems is extended to add most of the major file systems in Linux, even the experimental ones. This article adds ext2, jfs, xfs, btrfs, and reiserfs. As with the metadata benchmarks the purpose of this study is not to compare file systems and pick the “best” one (insert your definition of “best”). Rather, this study is an exploration of the performance of various Linux file systems using a single throughput benchmark. So the focus of this article is to explore how Linux file systems perform when IOzone is the benchmark.

Eclipse Luna for Fedora 20

If you are a Fedora Eclipse user, then you're probably saddened since the release of Eclipse Luna (4.4) because you are still using Eclipse Kepler (4.3) on Fedora 20. Well, be saddened no longer because Eclipse Luna is now available for Fedora 20 as a software collection! A software collection is simply a set of RPMs whose contents are isolated from the rest of your system such that they do not modify, overwrite or otherwise conflict with anything in the main Fedora repositories. This allows you install multiple versions of a software stack side-by-side, without them interfering with one another. More can be read about this mechanism on the software collections website. The Eclipse Luna software collection lives in a separate yum repository, which must be configured by clicking on this link to install the release package. Read more
