[Bug 63482] New: Application hang because of autoSizeColumn
https://bz.apache.org/bugzilla/show_bug.cgi?id=63482
Bug ID: 63482
Summary: Application hang because of autoSizeColumn
Product: POI
Version: 4.0.0-FINAL
Hardware: PC
Status: NEW
Severity: critical
Priority: P2
Component: XSSF
Assignee: dev@poi.apache.org
Reporter: rilot77@gmail.com
Target Milestone: ---
I have a problem with autoSizeColumn with small number of columns and data.
I have an application which generates XLSX files in different threads.
I have changed the POI version from 3.17 to 4.1.0 and the application became to
hang on the autoSizeColumn(sheet, true) line.
When I had removed this line or had changed to sheet.setColumnWidth(i,
SMALL_COLUMN_WIDTH) the problem was resolved.
There aren't excpetions in the log file!

Hi Dominik, thanks a lot for the effort put in your answer. However, it seems
to me that your measurements regard only Linux, while my problem and Vladimir's
original post concerns exporting on Windows. Am I missing something from your
info?

Small clarification: autoSizeColumn() works fine wit POI version 3.17 and Java
8

Oh, didn't see that, then we should do some more testing/verification on that
platform first.

I confirmed the problem.
It occured with POI-3.17 and POI-4.1.1 when it is used with Java 11.
With Java 8, there is no problem.
I've provided a snapshot of VisualVM CPU-profiling with POI-4.1.1 with both
JVM.
It's with a small sheet.
Sorry but I can't provide the application.

Sorry for the late response, digging some more it seems to be a known Java
problem as stated in
https://mail.openjdk.java.net/pipermail/2d-dev/2018-September/009454.html and
the associated links and it involves a new font layout engine (harfbuzz)
introduced in Java 9. For Java 9 you could still switch to the previous engine
(icu) but it was removed in Java 10, so no luck for my case with Java 11.
So fingers crossed to be fixed for Java 11 and if anyone knows more about this
on other JDK implementations, please let us know. I personally tried Oracle
JDK, Adopt and Corretto.

Also the sample-project on github shows the same timings.
22 seconds for JDK 8, more than 2 minutes for JDK 11 and 12, 6 seconds for JDK
13 and newer.
So I think we can close this issue now, JDK 13 and 14 are GA.

--- Comment #9 from Dominik Stadler <do...@gmx.at> ---
As the last comment on https://bugs.openjdk.java.net/browse/JDK-8202131 states,
this should be improved again in recent Java 11 and newer
A quick local test shows the following numbers of the reproducer from that
issue. As far as I see all of them run fairly quickly, only Java 12 seems to
run slower by a factor of 2, but this is not an LTS version of Java anyway.
Please verify if you still see a performance problem with a more recent version
of Java.

--- Comment #6 from contdespam@gmail.com ---
I can confirm the problem on Win10 + Java 11 + POI 4.1.1.
I created a small sample project which shows that on Java 8, an export of 2000
rows with 30 columns using SXSSF takes around 19 seconds while on Java 11 it
takes 2 minutes and 19 seconds.
As far as I can see, the difference comes from method
'org.apache.poi.ss.util.SheetUtil.getCellWidth(int, int, CellStyle, double,
AttributedString)', the call to 'new TextLayout(str.getIterator(),
fontRenderContext)' takes around 150,000 nanoseconds on Java 8 but around
1,180,000 nanoseconds on Java 11, almost 8 times as long.
Such an order of performance loss is critical on production environments where
much more rows are exported.
Is there anything expected on next release?
The small sample project should be available at
https://github.com/azmau/poi-perf

--- Comment #3 from Cody Lerum <co...@gmail.com> ---
I ran into this same issue today when making the move from Java 8 to Java 11
and from POI 3.17 to 4.1.0 and I've narrowed this down to a slowdown with Java
11. It doesn't matter if you are running 3.17 or 4.1.0
When running the simple reproducer (taken from the SSPerformanceTest) below
with POI 4.1.0
Elapsed 2.71 seconds for arguments [HSSF, 5000, 15, 1] on Java 1.8.0_212
Elapsed 35.08 seconds for arguments [HSSF, 5000, 15, 1] on Java 11.0.4
Elapsed 33.27 seconds for arguments [HSSF, 5000, 15, 1] on Java 12.0.1
The situation seems resolved in Java 13
Elapsed 3.44 seconds for arguments [HSSF, 5000, 15, 1] on Java 13
FYI this This is still an issue on the latest nightly pulled from AdoptOpenJDK:
Elapsed 37.13 seconds for arguments [HSSF, 5000, 15, 1] on Java 11.0.5
Commenting out the sheet.autoSizeColumn(i) yields:
Elapsed 0.54 seconds for arguments [HSSF, 5000, 15, 1] on Java 11.0.5

--- Comment #7 from PJ Fanning <fa...@yahoo.com> ---
No rewrite of SheetUtil is currently planned. TextLayout is a JavaRuntime
class, not a POI class. Rewriting POI not to use TextLayout is a big
undertaking.
Does your profile say what the hotspot is inside `new TextLayout` - there is a
lot of code called by that constructor?
Have you tried other JREs - newer versions or later JRE/JDK implementations?
