similar to: Sudden, dramatic performance drops with Glusterfs

Hi all I'm running since a couple of years a samba ver 3.0.33-3.29.el5_6.2 On a Red Hat 5 with kernel 2.6.18. Samba is member of a domain, with short name BNNAS03; some shares are using domain users, some are anonymous, open to a list of IPs. Suddenly is happening that, from my win7 computer is all ok if I call is with \\bnnas03 I see all shares, I can access and so on. If I call with

Hi all, I'm using Wine for a MotionCapturing Application (Qualisys). Although it's a quite recent application, it works well (I tried only data processing so far), but when I try to save a dataset (~180MB), it takes about 20 Minutes (!!) on my Computer. When I use it under VirtualBox (it does not run nicely there because of OpenGL), saving takes about 20 seconds. When I look at

Hi all, I have been a Wine user since about 2002 and have even contributed a few simple patches, but this is my first time on the forum. Anyway, I just wanted to make it known that wine 1.3.20 provides a dramatic increase in performance. Scrolling in the iTunes Music store no longer reminds me of pouring molasses (finally) and Photoshop Elements 5 is usable. Does anyone know what the magic was and

True, I just hoped you or one of the other devs might have some insight on reclaim behaviour that would provide a clue. I guess I'll try a

Dear R users/developers, simple comparison of code execution time of R 2.7.1 and R 2.7.2 shows a dramatic slowdown of the newer version. Rprof() identifies .Call function as a main cause (see the code below). What happened with R 2.7.2?

Hi all, This is not really a libvirt issue but I'm hoping some of the smart folks here will know more about this problem... We have noticed when running some HPC applications on our OpenStack (libvirt+KVM) cloud that the same application occasionally performs much worse (4-5x slowdown) than normal. We can reproduce this quite easily by filling pagecache (i.e. dd-ing a single large file to

Hi all, I've a 30TB hardware based RAID array. Wondering what you all thought of using ext4 over XFS. I've been a big XFS fan for years as I'm an Irix transplant but would like your opinions. This 30TB drive will be an NFS exported asset for my users housing home dirs and other frequently accessed files. - aurf

While looking into spec_ui, I decided to run the examples. The watir example works a little, but always chokes on the ''better than fudge'' spec (failure output below). Also, is there any command to pause the "browser"? If my connection slows, the test gets out of whack. The selenium example fails right away (output below). I do have the 0.9.0 selenium-rc

The tests are all running on 0.7.4. In installed 0.7.5 as follows: - sudo gem install rspec - script/plugin install svn://rubyforge.org/var/svn/rspec/tags/ REL_0_7_5_/vendor/rspec_on_rails/vendor/plugins/rspec - script/generate rspec ZenTest (3.4.1) is also installed. Here is what happens when I run the same tests that ran on 0.7.4. (By the way, Rails is build 5065). Any help is appreciated.

I'd like to mention that test does not allocate 30TB, it allocates 1TB, the rest, ~20TB, is reserved (but not actually used) for ASan shadow memory, it should not be a problem by itself. The test on your bot failed because it tried to reserve 27TB of memory, which is more than set by ulimit earlier in this test. I do not immediately see why it wants to reserve that much shadow for AArch64

I installed 0.7.5 and the corresponding Rails plugin. Now it seems that the rake command is: rake spec:autotest I immediately ran into several problems: 1. rspec_autotest.rb line 30 has curly quotes and makes Ruby choke 2. Same line, rails_spec is spelled solid, when it should have the underscore But fixing these didn''t get me back going. Now I have to have a rails_spec_server

So I have a function that does lapply's for me based on dimension. Currently only works for length(pivotColumns)=2 because I haven't fixed the rbinds. I have two versions. One runs WAYYY faster than the other. And I'm not sure why. Fast Version: fedb.ddplyWrapper2Fast <- function(data, pivotColumns, listNameFunctions, ...){ lapplyFunctionRecurse <- function(cdata, level=1,

In case anyone else is trying to make this work, here is what I did (Before 0.7.4 I had patched the regex in zentest redgreen, but that is not used any more) To use directly, it is very simple. In rspec_autotest/lib/ rspec_autotest.rb, add a -c to the spec_command in the initializer function: @spec_command = "spec -c --diff unified" This won''t help however if you want

Hi! I''m still struggling with RSpec to get it working with a Rails application, that does not use a database. I removed all the db:* dependencies from the RSpec targets, but it still wants to connect to a database. Any ideas? bye, Tobias ** Execute spec:models /usr/bin/ruby1.8 -I"/var/lib/gems/1.8/gems/rspec-0.7.5/lib"
