                Gevent vs asyncio with libuv
              
          
    The numbers claimed by this benchamark about Gevent [1] comparaed with the numbers got by Asyncio with the uvloop
and even with the default loop has left me a bit frozen. Ive repeated a few of them : gevent, asyncio, asyncio-uvloop and go for
the echo server and these are the numbers roughly:
For gevent
$ ./echo_client
685393 0.98KiB messages in 30 seconds
Latency: min 0.04ms; max 4.48ms; mean 0.126ms; std: 0.048ms (37.68%)
Latency distribution: 25% under 0.088ms; 50% under 0.122ms; 75% under 0.158ms; 90% under 0.182ms; 99% under 0.242ms; 99.99% under 0.91ms

                Git Speed
              
          
    How Fast is Git?

The web is full of benchmarks showing the supernatural speed of Git even with very big repositories, but unfortunately they use the wrong variable. Size is not important, but the number of files in the repository really is!
Why is that? Well, that's because Git works in a very different way compared to Synergy. You don't have to checkout a file in order to edit it; Git will do that for you automatically. But at what price?
The price is that for every Git operation that requires to know which files changed (git status, git commmit, etc etc) an lstat() call will be executed for every single file
Wow! So how does that perform on a fairly large repository? Let's find out! For this example I will use an example project, which has 19384 files in 1326 folders.
