I have often read that Fedora Logical RAID has better performance characteristics than a “BIOS” or “FAKE” RAID. That may be true in some cases. Today I dispelled that myth in regards to Nvidia BIOS RAID0 versus Fedora Logical RAID0. The test results were identical. Results were obtained with the latest Fedora 12 updates applied, and EXT4 was the format of the file systems. Note that in all but one test of the series, the Nvidia C55 based ASUS P5N-E SLi E8400 system using a standard WDC 5000AAKS running Fedora 11 with an EXT3 partition outperformed an Evga 780i FTW QX9650 system using two WDC 5000AAKS in RAID0 AND using an Intel X25M SSD. Check the results at the link at the top of this article.
There are several files available from the following server for the fix related to “Slow” kickoff application launcher response.
After installing the necessary files, my symptoms with this issue abated. This was not an issue when using the default nouveau driver. I am using the nvidia driver via the methods suggested by leigh123linux at the Fedora Forums.
The nouveau driver does not provide glx direct rendering support. The nvidia driver does.
After the latest versions were installed and I rebooted my screen response became exceptionally quick.
There is now a way to install F11 x64 or i686 on a Nvidia or Intel ICH10R RAID that was initially created using Windows. Install Fedora 9 x64 or i686 from the Full install DVD. Partition as needed. Once that is complete, use a minimal install set for Fedora 9. We do this for the ability to slice the partitions safely. Next use a F11 DVD to install on the existing partition and select format the existing partition. Do NOT delete the existing partition or you will end up with a segmentation fault in Anaconda. It has been a long time coming and this is not an elegant solution but you can now have F11 installed on an NVIDIA C55 chip set RAID or INTEL ICH10R chip set RAID that was originally formatted or configured using Windows. The change is dramatic. F11 boots on my E8400 Core 2 Duo 20 seconds faster with F11 than with F10. Fedora 10 will never get fixed for this issue. Fedora 13 is doing a fair job without workarounds.
Fedora 11 x64 as it is currently is not capable of creating a partition on a ICH10R or Nvidia C55 RAID array. Fedora 10 x64 is also impacted. Fedora 9 x64 works as expected. I hope this saves a few of you some grief in attempting the installation.
There was a press release from Nvidia related to the performance differences between Intel Core 2 Duo, and Intel i7 processors. Basically they observed that the Core 2 Duo was just as fast in real world games tests.
They just published this article last week.
I published documented findings to this same effect back on March 12, 2009. Nvidia, if you and yours have an interest in being on the edge or close to it, you really need to pick up your pace.
