Java IO Faster Than NIO – Old is New Again!
FFmpeg’s VP8 Decoder 62% Faster Than Google’s
The FFmpeg team has completed the initial implementation of their new VP8 decoder and early benchmarks are showing it up to 62% faster than Google’s own VP8 decoder: libvpx.
A few weeks ago we covered the announcement that the FFmpeg video-codec team had decided to build their own VP8 decoder and did an initial implementation in [...]
Odd ReadyNAS NV+ Performance Boost Tip: Disable Jumbo Frames
A real quick tip for folks experiencing abysmal Read/Write performance on their ReadyNAS devices: Try disabling Jumbo Frames.
Jumb Frames only benefit you if your client supports it, any switches or routers you are connecting through support it, and the ReadyNAS you are ultimately communicating with support it.
If any links in that chain do not support [...]
Sunsceen Performance and Safety Testing Guide
The results were recently published of an independent study done by the EWG. They took over 500 store bought sunscreens and put them to the test. And the results were pretty shocking.
The worst offender being “Banana Boat Beach Baby Max” with an advertised SPF rating of 100, but after performing an industry standard test, it [...]
Chinese Version of Cirque du Soleil
This is an unbelievably talented troop of Chinese gymnasts performing a routine that I can only imagine Jesus might attempt:
Yes, yes you just saw a 4-man pole formed by people front-flipping inside of the pole to make it taller… I’m going to start learning Chinese so when they take us over, I can be assimilated easier.
Seagate’s Hybrid Momentus XT Hard Drive Performance Shortcomings
A few weeks ago Seagate announced the world’s first (successful) hybrid spindle-hard-drive/SSD-hard-drive. It was a combination of a 500GB spindle drive like their standard Barracuda series matched with 4GB of flash memory inside of the hard drive to give some of the benefits that SSD hard drives enjoy without incurring the cost of all that flash memory; [...]
Funny Opera Browser Speed Test
I suppose Google put together a Rube-Goldberg “speed test” of the Chrome browser and Opera decided to 1-up them with what I found a hugely entertaining and funny “Opera Browser vs a Potato” speed test video.
A lot of what I found to be gold about this video was that it’s more like an SNL skit [...]
Increase WordPress Performance on Apache with Worker MPM, PHP and mod_fcgid
This is a continuation of two previous posts about Apache performance running PHP-apps like WordPress. One was on running PHP via CGI and the other was on running Apache with the thread-based “Worker” MPM instead of the default “Prefork” MPM.
As mentioned in the other posts (incase you don’t want to read them… I don’t blame [...]
Optimizing WordPress Page-Load Pauses with PHP-CGI
For the last 6-months I’ve been trying to deal with mysterious “page load pause” issues with WordPress on my Apache/prefork/mod_php setup. Server load was low, hardware was a 4GB 2-core machine, spent 4 months of that time tweaking MaxClients and other Apache prefork settings until I finally gave up.
The behavior I was seeing is hitting the [...]
NVIDIA GeForce 480 – 6 months to Play Catch-up
Wow, what a disappointment. After all the NVIDIA-spewed hype about beating down ATI when their DX 11 cards were finally out, the reviews are finally in on the brand new NVIDIA 480 and 470 cards and I’ll save you the trouble of reading every single review out there like I just did:
NVIDIA’s GeForce 480 performs [...]

Myriad Announced Dalvik Turbo – Android Gets 3x Speedup
Engadget covered a story about the company Myriad Group AG that was showing off their “Dalvik Turbo VM” product at the Mobile World Congress. At their booth they had an OpenGL demo running on two Google Ion (HTC Magic) phones, about 1/2 the horsepower of a Nexus One.
In this particular “spinning 3D box” demo, the [...]

Disable 'Indexing' in Windows 7 to Speed Up Deletion of Many Files
I’ve been on Windows 7 since the RC was released — that coupled with the fact that I’m a blogger makes me an expert, you should trust me and take my word on everything unconditionally — and while I’ve been overall pretty happy (20 tips and tricks, 8GB performance) there have been a few niggles [...]
Nexus One 'Poor T-Mobile 3G Signal' Issue Discovered
Update #1: Google has responded to the long thread with an announcement that an over-the-air (OTA) update to help make the 3G connections more stable in 3G-covered areas will be coming out, but if you are outside of T-Mobile’s 3G coverage area (which is small) there will be no change in experience for you. Release [...]
