I have this problem on my workstation. The computer would effectively freeze for 2-5 seconds for no apparent reason, then continue as normal. While frozen the mouse would still be movable, but only on one of screens in my multi-screen setup. What can be the likely cause.

CPU: i7-920

I have an interent connection with the speed of 4000k bits up and down. I want to do port based traffic shaping on a ubuntu machine, which acts as router. eth0 is the WAN interface. This is how I would like to allocate bandwidth:
For ports 80 and 445 the bandwidth usage can go upto 90%
For ports above 1024 upto 65535 the bandwidth usage can…

I have used Windows 7 to create an image of my existing standard 160GB HD and copied this image back to a bigger 500GB Seagate hybrid drive. After copying the image to the hybrid I had to resize the partition, which was fine but after rebooting a few times to "teach" the hybrid, I have no increase in boot speed. It still takes 20-25 seconds…
I am wondering if a typical while(true) ServerSocket listen loop takes an entire core to wait and accept a client connection (Even when implementing runnable and using Thread .start())
I am implementing a type of distributed computing cluster and each computer needs every core it has for computation. A Master node needs to communicate with…
Hello,
Im using Collections.sort() to sort a LinkedList whose elements implements Comparable interface, so they are sorted in a natural order. In the javadoc documentation its said this method uses mergesort algorithm wich has n*log(n) performance.
My question is if there is a more efficient algorithm to sort my LinkedList?
The size of…
We've been using Server2008R2 with Hyper-V for a couple of years now and chose it at the time because of its ability to make use of Intel SpeedStep and AMD PowerNow!
Now with Server 2012 and Hyper-V V3, all power management abilities seem to be gone. The CPUs are always at full speed and our servers need twice the energy as before while…
Suppose I have a 10BASE-T device, but everything else on my network is 100BASE-T or faster. When I attach the 10Mbit device, one of two things could happen:
It could be passed through as 10BASE-T, making whatever it's connected to slow down to 10BASE-T, or
It could be converted to a higher speed.
I'm looking for all the plausible…

I am running Redmine under IIS using Zoo. Installation was done using the Web Platform Installer and the default configuration has not been touched.
However, when using the application, the first requests take very long to complete (sometimes more than one minute). During that time, the ruby.exe causes some CPU load (about…
What's the most exotic, coolest, unique, or interesting machine you've worked on? Most of us work on machines with x86 architectures using some Windows or Linux variant. I'm sure there are those of you out there who are working on or have worked on machines with experimental architecures, or operating systems. Maybe you…

I store all of my images, js, and css files on a separate domain to try and speed up page load times (it isn't a CDN, just a separate domain on the same server). This works fine for 99% of the users, 99% of the time. However, there are users that randomly are unable to connect to the static content domain for periods of…

I'm thinking about using semantic (web) technogies like RDF and OWL in an application on mobile devices. Currently I'm targeting android, but I'd also be interested in the possibilities on the iPhone and on J2ME.
I would like to use a lib instead of implementing everything from scratch. I know that there are…
I'm going to build a ZFS file server from FreeBSD. I learned recently that I can't expand a RAIDZ udev once it's part of the pool. That's a problem since I'm a home user and will probably add one disk a year tops.
But what if I set copies=3 against my entire pool and just throw individual drives into the…
I inherited a windows server 2003 coldfusion 7 server a few weeks ago. Today a network cable was unplugged by accident from the server. On plugging it back in, pages were NOT loading at all. Rather, we were receiving a generic coldfusion error page. After restarting IIS several times and coldfusion…

javascript
actionscript bytecode or a…
I'm trying to diagnose a slow filesystem issue on a server I look after. It's been ongoing for quite some time, and I've run out of ideas as to what I can try. Here's the thick of it.
