Hello fellow Commando users! First thread (and post for that matter). Cutting to the chase: While I know there is a thread elsewhere on androidforums about this, I'm sharing these tips as a Commando user. Tech Stuff: Casio G'zOne Commando Android 2.3.3 rooted Adata Class 10 16GB microSD card ...what else am I missing??? I've gotten a significant increase in SD read speeds on my Commando as a result of increasing the SD cache size. The default is 128k. You can change the value using the free app SD Booster. It changes the value found in /sys/devices/virtual/bdi/179:0/read_ahead_kb and can set the value upon boot if you choose, otherwise it reverts to 128k. I used SD Tools to benchmark the r/w speeds. NOTE: Apparently, closing and reopening SD Tools between each test provides more accurate results. I dunno for sure, but I did it anyway. ALSO, I didn't test in numerical order. I started with 2048k, then 128k, 4096k, 1024k, and bounced around some more. I'm not listing write speeds because it only increased by a couple MB at most and never went over 13MB/s. That's not possible to increase much anyway. Read Speeds: 128k: ~20MB/s 1024k: ~31MB/s 2048k: ~29MB/s 3072k: ~32MB/s 4096k: ~30MB/s 5120k: ~31MB/s I had caught on to the possibility that odd multiples of 1024 were giving faster read speeds, so I went up even more out of curiosity. 7168k: ~32MB/s 8192k: ~31MB/s I'm 100% sure your results will vary. What I really wanted to communicate is the interesting find about the odd multiples of 1024, and hopefully bring all this to those Commandos that wish to be the next Seabiscuit. DISCLAIMER: While in my research I did not find anything to be concerned about with raising the cache size, I didn't write any of the apps and am not forcing you to do this. Thus, I cannot be blamed if your phone grows solar gills and flies into the Sun... or something. Have anything to correct/share? Please enlighten me!
