Magento 2 goes terribly slow (Developer mode)

Tags:

Recently I started developing magento 2 projects.

First I tried on Windows with xampp and it was a mess... every refresh page was a nightmare, about 30-40sec to load the page. I read about it, that Windows system files is so slow working with magento because the large structure it has, and the article almmost was forcing you to use linux for developing on magento projects.

The problem is I need Windows for another company apps that only works on Windows, I tried to install a virtual machine with Virtualbox, it improved a bit... but the fact I'm working on a virtual machine pissed me off...

The next solution and I'm working currently, is using vagrant. Okay, I feel good developing on this way but it keeps going slow... 15-20s...

My config on Vagrant is 5120MB (pc has 8GB) and use all my pc 4 cores.

I'm feeling so bad working like this... when I was working on my previous projects, with symfony/Laravel/Codeigniter, was like:

write some lines of code, tab to browser, F5, INSTANTLY see changes.

On M2: write some lines of code, tab to browser, F5, wait... wait... okay now it refreshes the page, but it's not loaded, wait... wait... hmmm almost... okay. No changes but I cleaned the cache... ohhh I guess I had to remove static files too. Go for it... wait again...

God... There's no way M2 goes faster? I'm only asking 5s or something like that... it's just I'm feeling so dumb looking the screen waiting all the time...

For aclarations, I'm only asking for development mode, I tried had to install another project of magento on production mode for testing things faster and then it's okay fluid as hell compared with developer mode... because... omg... just try to do an order workflow again and again...

Well that's all... The only thing I didn't try is using Linux environment on the computer... but it's just the same as using vagrant... I don't understand... how are you developing M2 developers? in special frontend developers... I don't believe they are working the same way as me... waiting 20sec for loading the pages + cleaning cache + removing static files, etc.

Details: I tried everything with vagrant but don't improve, I'm currently on Ubuntu 15.04, Apache 2.4, PHP 5.6 (I tried 7 but still the same) mysql 5.6

Why is Magento 2 so slow?

Magento is so slow because you may be using unnecessary themes, extensions, and customizations. Also, Slow hardware, far hosting server, not caching data, not enabling flat catalog, not minifying CSS and JS, and not updating your store lead to Magento's slow performance.

Which mode is faster in Magento 2?

Magento 2 has three running modes: default, developer and production. Production mode is the fastest one and it is used to power live sites.

Why is Magento admin so slow?

One of the basic reasons why website administrators experience slow performance while saving a product is because of reindexing. Whenever you save a product, the Magento backend starts to reindex, and since you have a lot of products, it will take some time to complete. This causes unnecessary delays.

Vagrant + Windows + Magento2 = disaster. Vagrant + Apple + Magento2 = disaster.

Ubuntu + Magento2 = cooking on gas.

Simple modules, e.g. a widget, take many days more than the expected 2-3 hours and it is not possible to remember what you are doing if it takes a minute to open a page, particularly so if you have to clear caches, compile, upgrade or anything else that should take no-time-at-all.

This I have experienced first hand, from working in an office where the options are Mac or Windows. After spending a whole day trying to change the template directive and failing to make one configuration change in 8 hours, I thought about giving it a go on a linux box to see if I had gone mad or if this Vagrant contrivance is as helpful as that drunken bum sleeping rough in the park down the road.

The aged linux box with anaemic RAM, an old SSD, stock Apache and no fancy cache things completed the task without problem, I was able to switch between developer and production modes effortlessly and get what had taken me days to not do done in minutes.

The work machine was 8th generation i7, the Vagrant setup was very much someone's baby and a lot of time had been spent building the beast. Yet tectonic plates move faster. Vagrant and virtualisation might be fashionable but it is no use for M2 development. In fact I installed M2 and did all the db and vhost setup for it in less time than it takes for a Vagrant box to build.

As for performance, since M2 on a basic linux setup is 10x faster than some clumsy Vagrant effort, it is easy to see where the real speed problems of Magento 2 are. If you fire up Lighthouse in Chrome you will see TTFB is absolutely fine but the performance halves if you minify and merge the JS + CSS. This is because M2 has a megabyte of scripts to download. This is the performance killer. If you are working on a Vagrant box then you will never see this and not have the speed to fix it. By fix it I mean write a proper theme that doesn't have nonsense such as jQuery loading on every page.

For production you need something that scales so you can get the normal speed enhancements going for that, e.g. Redis, opcode caching, Varnish, tweaked php-fpm, tweaked MySQL/MariaDB. If you are developing on Linux then you can test these things on localhost knowing they will work fine on production. With that abomination that is Vagrant you will be dabbling with these optimisations prematurely because you are hoping and praying for a performant machine because you need to get work done. However, in so doing, and with the absence of native speed, you will not get anything done.

If you don't have a spare machine to put linux on then just go to the local tip, get any PC, shove an SSD in it and you are good to go.
