I am using Neo4j installed on Linux Server RHEL 7.4 having below browser and neo4j version
Neo4j Browser version: 3.2.18
Neo4j Server version: 3.5.4
Neo4j Browser responding very slowly while trying to run or edit the query in browser.
I am using Google Chrome Browser.
My primary OS is OpenSuse 42.3, which equivalent to SLES 12. It has KDE 5.8 and Gnome 3.20. My preferred desktop is always KDE--I used Gnome in the past but found it to be inferior to KDE. When they messed with the last decent version of it, I have disliked Gnome since inception of v3. If am forced to use it--I revert back to Gnome Classic.
I previously used your exact configuration months ago in KDE with no performance issues. I am currently at Browser 3.20 and my databases at 3.5.6 & 3.5.7 with no performance issues. I have not used Gnome recently, I could check to to see if running Neo4j in the Gnome desktop makes a difference.
I do not like Chrome--I use FireFox. Try loading FireFox and see if you get the same performance.
Also, is your database properly configured for its memory allocation? Meaning, it may not be the Browser but the Browser waiting for the database to report back.
