Hello all,

First, my admirations for the great work you guys are doing with CM.

I started using CM since version 7.0.1 and it was the first ROM on my N1. Since then I noticed that when connecting through USB the data transfer speeds are really slow (1.5 MBps tops). I thought it was a phone issue but when connecting via recovery or different  ROMs speeds go up to 10 MBps. The problem is still present in 7.1.0.

I know it's a frequent problem on N1 but couldn't find a solution. Please help. I want CM back on my N1.

The only "solution" I am currently aware of is to use the app called Multi mount in the market to mount your sdcard to the computer.

What is the contents of /sys/devices/virtual/bdi/179:0/read_ahead_kb on the phone?

I increased mine to 2048.

I have the following in /data/local/userinit.sh

sdra=/sys/devices/virtual/bdi/179:0/read_ahead_kb
test -f $sdra && echo 2048 > $sdra
