similar to: how to counteract slowdown

I like the fact that in subtracting two time series objects that there is some effort to align the series. So if I have a time series of that begins at 1 and one that begins at 2 a subtraction operation makes sure that the proper values are subtracted. But I am unclear as to the best way to build a time series with "holes". say that I have data for "day" 1,2,6,7 in one time

Ever since we have installed OCFS2, we have had extremely slow performance in the ocfs2console. It can take us over 30 minutes to do the simplest tasks. We do not have this type of performance with other xwindows applications on our server. Does anyone have any performance improvement suggestions for the ocfs2console? Thanks, Reid

Hi, I'd like to use a flash drive as a journal device, with the purpose of keeping the main disk drive spun down as long as possible. I have a couple of questions: 1) Does the journaling code spread write accesses to the journal device evenly, as I hope, or are there blocks that are particularly "hot"? I.e., do I have to worry about the flash device dying quickly because of

Hi all, We are observing a consistent interval of about 4 minutes at which there are large sustained writes to disk that causes mysqld to block and not respond for the entire period. We are using data=journal with a 128M journal and the filesystem is 150GB in size. We get about 300kb/sec in writes and that will jump to about 2000kb/sec during the periods of large sustained writes. Those

This is a quick and dirty .ctags file that makes basic navigation possible with vim and ctags, great if you have multiple files: --langdef=puppet --langmap=puppet:.pp --regex-puppet=/^class[ \t]*([a-zA-Z0-9_\-]+)[ \t]*/\1/d,definition/ --regex-puppet=/^site[ \t]*([a-zA-Z0-9_\-]+)[ \t]*/\1/d,definition/ --regex-puppet=/^node[ \t]*([a-zA-Z0-9_\-]+)[ \t]*/\1/d,definition/ --regex-puppet=/^define[

Hi, I am trying to install Gnumeric in CentOS 4 and I can't. It complains about quite a few dependencies failing. It suggested installing some postgresql librairies, openldap librairies... I did that, now I still get: dependencies failed: libmdb/libmdbsq/libsqlite/libxbase/libtds. Is there a yum repository that has them or a yum repository for gnumeric? I have tried Dag, he does not, he

Hi, we are running a ceph cluster with btrfs as it''s base filesystem (kernel 3.0). At the beginning everything worked very well, but after a few days (2-3) things are getting very slow. When I look at the object store servers I see heavy disk-i/o on the btrfs filesystems (disk utilization is between 60% and 100%). I also did some tracing on the Cepp-Object-Store-Daemon, but I''m

Hi all, Just dropping a line here because I have recently release a plugin that some of you might find interesting or get a little use out of. I call it Railmail. In a nutshell, it traps any mail sent through ActionMailer (when the delivery_method is set to :railmail), stores it in a database, and provides an interface to view those messages. My initial motivation for the plugin was gmail:

Hi there, We're currently attempting to explain a slowdown of an LVQ-type parallel analysis we're working on. We are benchmarking our analysis running over openMosix against the same running via SNOW for R. Both perform similarly on small datasets, but on large datasets SNOW drastically outperforms openMosix. However, these results are achieve running SNOW on the default RedHat

Thanks for acting on this so quickly. Yes, the latest commit fixed the problem. I figured it would be a small patch but wasn't sure where to make the change.

Hello, after the update from Samba version 2.2.8a to samba-3.0.4 I have a big slowdown. The configuration at the moment is like this: samba1 --> Still running 2.2.8a on Solaris. Configured as a PDC. Workgroup A samba2 --> 3.0.4 on Solaris Workgroup A security = server; password server = samba1 samba3 --> 3.0.4 on Solaris Workgroup

First of all Hi everybody and thanks for this cool software called "wine" Well I've been looking for Help... I Know there is a lot about it... but I just wanted to know.... I have an AMD sempron 2500+ Gforce 6200 (256 MB), 1GB ram, with Ubuntu 8.10, Kde 4.1 (desktop effects disabled, no slowdowns in opengl aplications). Everything is ok, no sound problem.. no grafic problem. For

I'm getting very strange issue with rsync on one of my servers. I spent many days trying to figure it out myself, playing with options, settings etc but had no luck and now only thing is left for me to write to this mailing list. I'm using rsync to backup data from one server to another. And I see data is transferred extremely slowly. It seems to halt for a long period of time, after send

Hi, I''m running RoR on a debian woody virtual machine with 256mb of ram. Over time the ruby proces balloons to 90% of memory - and starts taking 5-10 seconds to respond to a request. I''m starting the server via: ruby script/server -e development -b 192.168.x.x Where should I be looking to get an idea of what''s causing this "memory leak"? I''d like

Is there something currently going on on the rspec trunk that causes a massive slowdown when running rake spec and autotest (without spec_server)? I updated to the latest trunk yesterday and the time needed to run the specs of my app jumped from ~20 seconds to more than a minute. The weird thing is that if I run the rake spec tasks separately (controllers, models, views, helpers), they
