Here's a list of commands that you should execute and then share the output to someone who can help you figure out what resource is the bottleneck in your system. Note, it requires the sysstat and procps packages (ubuntu and RHEL and its derivatives): uptime vmstat 1 10 iostat -xN 2 10 mpstat -P ALL 3 10 pidstat 1 10 free -mw (or free -m, if your OS doesn't support -w) uptime is to see the load averages on the system. vmstat is mostly used to tell if the system is swapping or not. If you see significant numbers in the 'si' and 'so' columns, your system is most likely swapping (using the hard drive as RAM), which usually slows performance a lot. iostat is mostly used to determine if your disk subsystem is not able to cope with the load. If you see one or more lines that shows 100 or close almost constantly, it is probably the case. If it is your swap volume, you probably saw numbers in the 'si' and 'so' columns in the vmsta...
Hi, I've been using UltraVNC for a while and while commenting on an article on UnixTutorials , I thought it would be a good idea to share my knowledge. First, I must say that UltraVNC is a free version of VNC that has more features than the free version of RealVNC (thanks for sharing the code, though...). It supports encryption and Active Directory authentication, and a few other nice features. But what I want to talk about today is the Single-Click feature (SC). Very useful... Example situation: One of your client went to a foreign country and he wants to configure the e-mail client of a laptop he borrowed there. VNC is not installed. You can spend an hour telling him over the phone how to configure Outlook or Thunderbird, or just tell him to go to your website, download a single executable, and take control of the PC and configure it. How to proceed: Make sure the VNC (or UltraVNC, for the rest of the text) viewer is loaded on your computer, in listen mode. You can access...
At work we have been using Borland's Starteam for a while for our SCMS (Source Code Management System). I don't know it is good or bad, as we have simple team, but when I asked for additionnal licences, I found out that their prices are very high: 1 Named user: 750$, 1 Concurrent user: 3900 (discounted by 50% at the moment I asked for a quote). And add to that 22% yearly maintenance cost. As we already started using Subversion for other projects, we decided to move from Starteam to Subversion for all of our projects, but our concern was of course how to import all the project versions from Starteam to Subversion. Thanks to a nice company named Polarion, it is possible with their svnimporter tool http://www.polarion.com/downloads/svn.php . This tool is available to migrate from other SCMS to Subversion with support for CVS, PVCS, VSS, ClearCase, MKS and Starteam. It took me some time to figure out how to run the tool (which is java-based). At first I jus...
