Material editor slow

Is this faster in new CONNECT ?

I mean - everytime  i use material editior -  even only change name - i must waiting and waiting. Why ?

Its only text in database i think. I change the SSD to the NVME and still this is so slow  ,  material editor read something - geometry ? why ?  I only want to change name or add new material.

See attachments.... Its taking many seconds....   Maybe i not understand this - but for example Google search can find many images, words, pages in one second,  and local material editior is working slow.

It is so frustrating after years.
