mktorrent with pthreads

The ultra documentation points to the Ubuntu version of mktorrent which is single threaded. This feedback request will explain how to make torrent creation multi-threaded using pthreads. It will make torrent creation 4 to 8 times faster on ultra infrastructure. The practical use case is a service enhancement for the ruTorrent web portal.

It’s required to the build-essential package to perform this task.

Step 1: Download the source files.

curl -sL https://github.com/pobrn/mktorrent/archive/v1.1.zip -o mktorrent.zip

Step 2: Unzip the source files and change directory.

unzip -d mktorrent -j mktorrent.zip && cd mtorrent

Step 3: Update the build configuration with these recommended values.

 echo "CC = gcc" >> Makefile	

 echo "CFLAGS = -w -flto -O3" >> Makefile

 echo "USE_PTHREADS = 1" >> Makefile

 echo "USE_OPENSSL = 1" >> Makefile

Step 4: Build the software and install it to the same prefix.

make -j$(nproc)

make install PREFIX=/usr
