mgo insert loop - parallelized vs. standard - The point of this test isn't to check the throughput of inserting 10000 records using mgo, but to explore the difference between doing standard and parallel loops using an overblown common case. Out of curiosity I have added a bulk insert benchmark at the bottom, which is clearly the most powerful wa…

NGINX tuning for best performance

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Activate and deactivate commands for working with conda environments in the fish shell. Currently assumes you are switching to a named environment, not specifying a directory.
function condalist -d 'List conda environments.'
for dir in (ls $HOME/miniconda3/envs)
echo $dir
end
end
function condactivate -d 'Activate a conda environment' -a cenv
if test -z $cenv
echo 'Usage: condactivate <env name>'
