Polling Searches on GHE

How can you determine what is polling your GitHub Enterprise system? If you suspect polling, this data will help you pinpoint where it is coming from. Don't just tell your users "stop polling", get the data and tell them where it is coming from.

Number of requests in 10 minute intervals

When reviewed over a 24-hour period, consistent numbers in non-peak hours indicates likely polling with short intervals. Longer polling intervals also stand out, often as a burst of high traffic each hour on the hour.

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.
