I am currently attempting to as we speak, but, I don't have any hard
numbers for you.
I have some numbers from a benchmark tool, but, there are so many factors
involved, I can't really tell you whether U2 performance is 30 times
faster... Although I'm hoping this week I can get Universe installed
Hi,
Take a look at http://www.easyco.com/index.htm. The performance of these
devices is amazing plus they are much lower cost than the usual SSD
alternatives.
We have users running these who may be willing to give an unbiased opinion.

I think the first thing you need to assess tho is - is it the diskio that is
the bottleneck - if you have a *nix system with plenty of ram, you get a
decent disk cache in ram. Analyse your wait on io stats for your processors,
if this is higher than your actual cpu utilisation then you do have a
You will need to consider that a RAM disk will use way more CPU, specially
in a multiuser environment. So that process that took forever it will run
faster, but you might be at risk of not leaving enough CPU power for the
rest.
We use Ram drives but not for everything.

Another option is replacing the drives with faster drives.
When I was last shopping for drives, I noticed that they have some 20,000rpm
drives out now
That with a good SAS controller that can handle the onslaught of data on

Or possibly, using multiple disk controllers with faster
+1 for easyco's SSD stuff. I have worked with it on smaller
implementations. It works very well. The same should apply on anything
large.
In a nutshell, their stuff I believe takes the random reads and writes at
the OS level and turns them into sequential reads and writes, which is
faster and

IMO FusionIO has the best memory-drive devices for small size high volume
IOPs. Facebook is one of FusionIO's largest customers. Their devices are not
inexpensive but they are solid, fast and the support is great. We barely
touch the write capacity of our 80GB board. It's the read speed and r/w
Hi all,
I am installing Universe on a system which already had RHEL 6 installed on and
whoever installed it pretty much install all packages so it is very bloated.
Can someone provide me with a list of packages that they have installed on the
RHEL 6 server?
I realise there will be subtle
