libshape is library for limiting the download rate of programs.

libshape library works entirely in user space with existing programs through LD_PRELOAD.

Are tested with threaded programs. This limiting is done entirely in user space. You only need to start Your program with

$ LIBSHAPE_CFG=/home/user/.libshape/program1
LD_PRELOAD=libshape.so
./program1

to limit download rate to 14Kbps You need to convert this rate to Bps:

$ echo $[14 * 1024 / 8] > /home/user/.libshape/program1

You can't dissable limiter, but you can set it to very high limit.

You can change download rate on the fly. Changes will occur in 1-5 seconds, becous there are some buffers in kernel space.
