• Posted Perl performance evolution over the last decade to Dimitrios Kechagias

  I was reading recently about some significant Python 3.11 performance improvements, and I was wondering whether Perl 5 still gets significant performance improvements on each version - even though it might be more mature, thus more optimized in the first…

• Commented on What happened to Perl 7?
  IMHO announcing Perl 7, which was picked up by the non-perl community as clear "signs of life" from what they thought of as an irrelevant/dying language, and then taking it back was quite a big step backwards, so I'd thought...
• Commented on Cloud Provider Performance Comparison - Perl & more
  Thanks for the comment. The reason I included just Linode and Digital Ocean from the "smaller" providers, is because they have good reputation (Linode's been around for almost 20 years now) and I personally have good experience with them. I...
• Posted Cloud Provider Performance Comparison - Perl & more to Dimitrios Kechagias
  Last year, impressed with the apparent speed of an M1 Mac Mini I bought to try out, I explored its perl performance and wrote about it in a blog post. I used mainly my own benchmarks which were mostly…
• Commented on Perl performance on Apple M1
  A bit late, but you might enjoy my DKBench, which is similar to what I did above, in a single test-suite, made for subsequent perl benchmarking which will probably end up in another blog post....
• Commented on Perl performance on Apple M1
  I wrote about it above, it was my first idea, which is why I ran powermetrics to make sure, and indeed it is still using the performance cores, same profile as before the sleep/wake cycle, so no idea what happens....
• Commented on Perl performance on Apple M1
  Apart from the last two that are proprietary, all the others have the full code here (if they are programs, otherwise the exact command I run with time). Not sure what more a github repo would do? Is there something...
• Posted Perl performance on Apple M1 to Dimitrios Kechagias

  I recently got an Apple M1 Mac Mini, half out of curiosity, half because it was exactly what I would need: I have a low end Mac just to try out things like new Xcode betas etc, like a "canary" machine. My old 2012 Mac Mini stopped getting official Apple…

• Posted Speeding Up Perl Test Suites & Test2::Aggregate to Dimitrios Kechagias

  I gave a talk at TPC 2019 based on my experiences speeding up the Perl test suite at room/roommate finding service SpareRoom,…

• Dean commented on Perl performance on Apple M1

  What I mean is to wrap up what you can in a script so its quick and easy for someone to replicate. Spitting out a result that can be compared to other results.

• Smylers commented on What happened to Perl 7?

  Thank you for such a clear update. As somebody who only manages intermittently to follow what's happening with the Perl core, this is really useful, and explains several things I'd be wondering about.
