php - Advanced Custom Fields is slow on admin screens -

-

i'm using acf set series of slots in page. admin screen contains series of flexible fields, each of can 1 of following:

  • post
  • category
  • tag

works great on front end. can drag-and-drop, choose posts/categories/tags etc. database , have time.

unfortunately when trying add new slot page on end, or load it, time taken add new row killing it. i've got few rows there, it's taking unacceptably long; i'm sure when add few more we'll start getting timeouts.

the information can find problem support thread on acf forums (https://support.advancedcustomfields.com/forums/topic/slow-backend-v-2-5-7/), says:

yeah, if you've got big database , try , use flexible fields it's gonna that.

i'm using acf-json no noticeable effect.

has else experienced problem? did work around it? or did have abandon?

(ideally solution keep flexible fields, they're client wants in situation - if there's solution enables them edit end in linear time, i'm interested in too.)

it's due way acf loads repeater fields , flexible fields. layouts in flexible fields loaded dom , hidden, , absolute ton of javascript logic applied of them. when click add new "slot", runs clone of hidden layout, , attaches necessary event handlers clone.

if check timeline page domcontentloaded vs load (final render event), domcontentloaded pretty fast of time, load (everything happens after html loaded) eats of time, , memory.

best i've been able activate new "delay initialization" option wysiwyg content fields, , disable "stylized ui" , "ajax" options select, checkbox, , radio fields.

ultimately, biggest issues come having nested repeaters/flexfields inside repeaters/flexifields. avoid nesting as can , page load time decrease significantly.

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
