Hello Peter, nice to virtually meet you!
I'm Luigi a sysadmin that work for sysdig
. I saw that you are the developer and maintainer of snapshot.debian.org
, i'm writing a krawler to get all the old debian linux-image and linux-kernel deb packages to be able to pre-compile a kernel probe for the sysdig project.
I noticed that the krawler is really slow and I did some profiling with cprofile (i'm using python).
The most amount of time is spent in the open function to grub the HTML from the website.
I was wondering if there are actions on you side that you can take to improve the performances of the website like add a CDN or a varnish cache o spot some bottleneck that you may have on your side?
Here an example of the time spent from an AWS instance on us-east-1 region to grub a page from snapshot.debian.org
(as you can see it took 20s):
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed

Looking forward to your reply.
