Hi,

I tried setting up and running mongodb as per the webfaction docs:

http://docs.webfaction.com/software/mongodb.html

When I start the db, I get this message:

** WARNING: You are running on a NUMA machine. We suggest launching mongod like this to avoid performance problems: numactl --interleave=all mongod [other options]

I tried that but I get: numactl: command not found

Any suggestions?

Thanks, Chuck

NUMA stands for Non-Uniform Memory Access, and the libraries for this are available here if you want to use them. Installation goes something like:

mkdir -p $HOME/src
cd $HOME/src
wget ftp://oss.sgi.com/www/projects/libnuma/download/numactl-2.0.8-rc4.tar.gz
tar -xzf numactl-2.0.8-rc4.tar.gz
cd numactl-2.0.8-rc4
make
mv libnuma.so.1 $HOME/lib
mv libnuma.so $HOME/lib
mv numactl $HOME/bin
export LD_LIBRARY_PATH=$HOME/lib

and then perhaps add export LD_LIBRARY_PATH=$HOME/lib in your $HOME/.bashrc file. Hope that helps!
