December 10, 2018 — Дискусионен панел за Гутенберг

December 10, 2018 — За онлайн магазините скоростта е дори още по-важна от колкото за един “стандартен” сайт. Всяка допълнителна секунда време за зареждане води до по-слаби резултати в продажбите и финансови загуби. Въпреки това, за много хора оптимизирането на онлайн магазини е сериозно предизвикателство. Основната причина е, че кеширането на страниците трябва да е по-фино настроено, за да не възпрепятства специфичните процеси на онлайн пазаруването, като запазване на продукти в индивидуалните кошници и други.

В тази лекция, ще покажа как да приложите техники за оптимизация, включително и правилно настройване на кеширането си за да постигнете един бърз и добре продаващ онлайн магазин.

October 15, 2017 — I have often come across this notion that WordPress isn’t ready for big projects by default and that a lot of customization is needed for it to work at a truly large scale. However, my personal experience with setting up and helping maintain several really big projects has made me heartfully disagree with this statement. In this talk I will show you how a truly scalable and redundant system can be created without the need to change anything in WordPress. Here are few of the topics I will cover:

— Multiple Web Nodes
How to properly use load balancers and how to set WordPress on multiple web nodes without making any application modifications.
— Multiple Database Nodes
How to have a redundant master-slave DB replication without WordPress even knowing about it.
— Shared Storage
How to organize your files on multiple nodes, replicate them and keep them in sync in the most efficient way.
— Handling Sessions
How to handle sessions properly and how to overcome other potential issues with huge sites hosted on high-availability, multi-node WordPress setups.

To achieve these three things you need to be on a constant watch out. Is your website live and accessible? Is it fast enough or visitors lose patience waiting for your page to open? In this talk, I will show you how to measure, optimize and prepare to scale resources to guarantee the availability and performance of your WordPress website.

November 11, 2016 — In this talk I will share with you the latest technologies that will make your WordPress website lightning fast and at the same time more efficient and easy to scale.

* How to analyze the performance of your site and see where optimization is needed.
* Which are the best technologies that can improve your WordPress loading times.
* How to maintain a healthy, efficient and easily scalable database
