Speaking from experience (I cannot go into detail on this point), and as Digimer pointed out, LSI seems to be the only choice for enterprise level, large scale deployments. If your concern is extremely long term deployments with verifiable data recovery options, software RAID is the only option, as you have strong guarantees that the implementation will never "die" as hardware RAID

Anyone made some performance comparison between XFS and ZFS with ZIL on SSD, in gluster environment ? I've tried to compare both on another SDS (LizardFS) and I haven't seen any tangible performance improvement. Is gluster different ?

...eloquent emails, but you still haven't shown an exact use case - why not write a unit test which demonstrates the benefit and post a patch for review? for those who are not familiar with gtest/gmock it makes it very clear.. Then the discussion moves from opinions and "feelings" to tangibles

Greetings I've searched to no avail so far... there is bound to be something more intelligible out there...??? I am playing with bonnie++ for the first time... May I please get some advise and list experience on using this or other disk subsystem benchmark programs properly with or without a GUI ? Test system in this case is a Compaq DL360 with 2 to 4 Gig DRAM and qty (2) 36Gig 10k drives

Hello, I'm using an SVM for predicting a model, but I'm most interested in the probability output. This is easy enough to calculate. My challenge is how to measure the relative performance of the SVM for different settings/parameters/etc. An AUC curve comes to mind, but I'm NOT interested in predicting true vs false. I am interested in finding the most accurate probability

I want to reiterate the benefit that underscore_names would bring. To be clear it's not my favorite style, but it does have a very concrete advantage which is that we have a very large subproject already using it. it doesn't make sense to do a purely aesthetic move that not everyone is going to agree on anyway, when we could do one with actual tangible value.

At each step, I think I am past most of the big hurdles. At each step, I find another one. I''m sharing these development stories on the list for a few reasons: 1. Perhaps some of you will find the stories interesting 2. To preserve my lessons in the list archives so I, or someone else, can (re)learn from them later 3. As a record of tangible progress 4. To vent some frustration

I've been searching around on the internet trying to find out about conduits and options for syncing programs with my Palm Pilot device. Google searches turn up a lot of discussion on the matter over a two or three year period, everything from people talking about doing it or how it should be done or how much they want it done. But I can't actually determine what, if any, tangible

I was interested in taking up the project ideas on adding profile driven optimization passes and improving alias analysis as this would give me a chance to carry forward and improve my current work and also contribute significantly in terms of tangibles.

I have strong C/C++ skills acquired by working on several projects including my thesis. Besides my thesis I have previously taken classes on Compilers, compi...

Hi :) My employer is looking to move a call centre to a new office, and has been increasingly frustrated with their legacy PBX (call-logging licensing and hardware upgrade costs). So I've stepped forth as the Open Source Pedant and suggested Asterisk so we can do all our own CallerID / call logging / analyses, and make use of IP Phones / teleworking, etc. The problem begins in that I only

Probably not. If there is, it would probably favor

I've had good results with using SSD as LVM cache for gluster bricks ( http://man7.org/linux/man-pages/man7/lvmcache.7.html). I still use XFS on bricks.

I think that 32-bit systems (especially ARM) may be short on memory so doubling the size of the table containing (potentially) all the functions may give a tangible overhead. I would even align the entries to 4 bytes (so 12 bytes per entry) on 32-bit platforms and to 8 bytes (so 24-bytes per entry) on 64-bit platforms, to improve CPU cache hits. What do you think?

This sounds like a great idea. LLVM definitely lacks some profile-driven optimizations. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University
