You could try to install jvisualvm and do CPU profiling to see what's taking so much \
time. For me (debian stretch, i3) it was gnome ATK wrapper that really killed the \
performance.

** [bugs:#4078] TDO DIR. CS jEdit 5.5 File Open (Slow) Bug 2019-03-20**
**Status:** open
**Group:** normal bug
**Labels:** trondelta TDO file open jEdit 5.5 2019
**Created:** Wed Mar 20, 2019 12:40 AM UTC by Mathias Hollstein

**Preamble:**
This is *not* a patch, complaint, question, feature request or plugin bug!
**Assumptions:**
TRON-DELTA.ORG Xubuntu SE 2018 (X64/AMD64)
Linux v4.15.0 (SMP x86-64)
jEdit v5.5.0 on OpenJDK JRE v1.8.0-191 and OpenJDK 64-Bit Server VM v25.191 mixed \
mode
* jEdit is configured via configuration menu, without hacks or illegal/no-working \
items loaded
* jEdit installed but inactive (for testing) plugins are:
Common Controls
ErrorList
Info Viewer
JDiffPlugin
LucenePlugin
MarkerSets
Process Shell
Project Viewer
Sessions
SideKick
WhiteSpace
**Bug Description:**
Opening several files at once (1 to ~10 files) works fine, while opening more, e.g. \
20, 30, 50 or 100 files at once, takes a long time (approx. 1 second per file) to \
open them.
For testing the /home/<username>/.jedit/ directory was backed-up and the erased. \
After starting jEdit with a fresh ~/.jedit directory and default configuration, the \
issue was still present when opening multiple files at once via the File --> Open. In \
jEdit version 4.x, opening even 300+ files at once was not an issue and took only a \
few seconds.
The more files are already opened / registered (BufferSet and EditBus) the longer \
each additional file open operation takes. With 100+ files the system slowly comes to \
a halt and 200+ files required me to switch TTY and kill jEdit after 20 minutes.
**Logs:**
- The follwong operations took 2 seconds, loading 4-5 files of 25 total

**Conclusion/Request:**
Since the migration to a new Linux and jEdit version something must have changed for \
the worse. Hopefully its just my setup and not a general issue.
Therefore, I politely ask the jEdit developers for help with tracking down the issue \
and reducing load times to a fraction of the current times.
Thanks for your help in advance!
