Subject Re: Performance Issue with 2.0.0 SNAPSHOT latest builds
Date Mon, 16 Nov 2015 14:48:02 GMT

Dear PDFBox team

I used the below code

	PrinterJob job = PrinterJob.getPrinterJob();  
        job.setPageable(new PDFPageable(document, Orientation.AUTO, true, 300) ) ; 
	Book book = new Book(); 
	book.append(new PDFPrintable(document, Scaling.ACTUAL_SIZE, true, 300), getPageFormat(receiptType)
, document.getNumberOfPages()); 
	job.setPageable(book); 
	PrintRequestAttributeSet attr = new HashPrintRequestAttributeSet();
	job.print(attr); 


I was able to get consistenlty performance of around 11 to 20 secs which is still slow.  With
0 dpis in both PDFPageable and PDFPrintable ctors result is inconsitent and time varies widely
from 20 to even 140 secs.

The input PDF file of 100KB, increased to 1MB. 

Creating a shareable sample PDF without confidential contents.  

But the problem with 300 dpi is printout resolution/quality is poor and blurred and no improvements
even with 600 dpi.  In my machine for 600 dpi throws out of memory exception. ( Wil JVM -Xm
option help?, did not try this ) 

Can we use 1.8.10?  It has performance but fonts and alignment issue?  
What changes have gone to 2.0 compared to 1.8.10?  
Is it adviceable to use 1.8.10?  (there also we got about 13 secs consistently but has alignment
and font issue)

Dear PDFBox team

Please use this mail as previous mail, forgot to attach code used and 1 question was already
answered and I removed that Q here.


Dear PDFBox team

Thanks for response to my earlier query on performance issue. The work around suggested was
to use the ctor PDFPageable(pdDocument, Orientation.AUTO, true, 300) while setting PrinterJob
pjob instead of PDFPageable(pdDocument), which is supposed to force the java.awt.print.PrinterJob
pjob.print() to use rasterization to render image which is supoosed to be faster.

 //pjob.setPageable(new PDFPageable(pdDocument));    // In my test this caused performance
issue ( 40 to 80 secs )
pjob.setPageable( new PDFPageable(pdDocument, Orientation.AUTO, true, 0) );  //In my test
this is about 3 times faster but still 18 to 30 sec. 
Below are my observations in unit test
Compared to 1 ( 40 to 80 sec) above, 2 was faster, but still it took 18 to 28 secs in multiple
rounds of test and 18 to 30 sec is also slow.
If I used 300 dpi, it was about 14 sec faster comapred with 0 dpi  ( last argument to PDFPageable
ctor, then the output file ( redirected to MS XPS file ) quality was not good. 
With 600 dpi,  awt.print.Printerjob pjob.print() throws out of memory exception as below
With 0 dpi results are not consistent, sometime printout took 60 sec, similar to using ctor
with one argument ( 1 ) above.

WARNING: Warning: You did not close a PDF Document

Input PDF file size is 118KB, whereas the output PDF generated by PDFBox 2.0.0 latest SNAPSHOT
build ( redirecting to MS XPS printer ) is about 1 MB
There was no alignment and font issue with 2.0 but slower
OutPut PDF generated by PDFBox was about 500 KB much less in size with PDFBox 1.8.10 and performance
was better ( 12 secs in 1.8.10) 
PDFBox 1.8.10 is faster but fonts are lighter ( it used default fonts and has thrown exception
) 

Please clarift the following:
Is 300  or non zero dpi mandatory, in  pjob.setPageable( new PDFPageable(pdDocument, Orientation.AUTO,
true, 300) ) to force awt to use rasterizing.  I saw in 2.0.0-RC1 code the other ctors of
PDFPageable(pdDocument) using default values for other 3 arguments and what made pjob.setPageable(
new PDFPageable(pdDocument, Orientation.AUTO, true, 0) ) faster, compared to pjob.setPageable(new
PDFPageable(pdDocument)) which in turn internally uses default 0 dpi as per RC1 source code.
Am i missing something. Whether ctor implementations are different in SNAPSHOT code post 2.0.0-RC1?
Why pjob.setPageable( new PDFPageable(pdDocument, Orientation.AUTO, true, 600) ) causes PrinterJob.print()
to throw out of memroy exception?  Is there any way to increase the dpi without increasing
the memory footprint?
Why even with pjob.setPageable( new PDFPageable(pdDocument, Orientation.AUTO, true, 0 ) ),
the print is slow 18 to 28 sec and with pjob.setPageable( new PDFPageable(pdDocument, Orientation.AUTO,
true, 0 ) ), there is only marginal improvement in performance of about 15 to 18 sec.
Will seting java property pdfbox.fontcache to a folder with write permission, will remove
admin privelage requirement to run PDFBox 2.0.0 to build font cache first time and store in
disk subsequent time
Is there a way to improve or roadmap to improve performace in 2.0.0, as 2.0.0 has lot of fixes
and improvements over 1.8.10, but 2.0 performance is main blocker for many of users.
Thanks a lot in advance for PDFBox teamÿ

Subject: Re: Performance Issue with 2.0.0 SNAPSHOT latest builds

Dear PDFBox team

Thanks for your response to below query.

I set the Java property value pdfbox.fontcache to JDK lib directory where fonts are ther ÿ(
D:\\Softwares\\Java\\jre7\\lib\\fonts ).
I set the java property within the code before PDFBox API calls usingÿ
System.setProperty("pdfbox.fontcache", "D:\\Softwares\\Java\\jre7\\lib\\fonts") ;
First time execution it took 140sec and created the cache file .pdfbox in the given directory
Subsequent time it took same 24 to 60 secs and no improvement in performance. ÿ
The difference noticed was, earlier ÿ.pdfbox file was created in user.home directory, now
given directory but on performance side no noticable difference.

My OS is MS Windows 7 home basic, since the user id has admin privilage, did not have admin
issue.ÿ
In another machine/work machine with admin user id/prvilage, PDFBox could create font cache,
but the performance was slow ( 30 sec + )

We use only Ariel and Time New Roman. ÿ
If the default font is chosen as Ariel in 1.8.10 code, that should be fine as 1.8.10 has performance,
but fonts are lighter.
Alternatively if 2.0.0 ÿis optimized for performance, that will be great.ÿ

FYI
PDF file ( redireting the print to MS XPS Printer type file ), the size of PDF file generated
in 1.8.10 is about 151 KB, whereas the size of PDF file created using 2.0 is 1152 KB ( about
10 times larger ).ÿ
It job.print() which takes lot of time. ÿTime profile output below

System.getproperty of pdfbox.fontcache = D:\Softwares\Java\jre7\lib\fonts
System.getproperty of user.home = C:\Users\Rangarajan
Nov 14, 2015 6:58:22 PM org.apache.pdfbox.cos.COSDocument finalize

Dear PDFBox Developers/Contributors


Thanks for reply, I tested with latest SNAPSHOT buildsÿ
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/preflight-app/2.0.0-SNAPSHOT/
------> build 1823
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/2.0.0-SNAPSHOT/
---------> build 1800 and 1801
ÿFont cache rebuild is not happening every time and it is able to use from local store, however

ÿCompared to PDFBox version 1.8.10, 2.0.0 SNAPSHOT builds performance is slow ÿ ( 1.8.10
about 13 seconds, but 2.0.0 SNAPSHOT 1800, 1801 takes 30 seconds. )

ÿMeasured the time difference between 1.8.10 and 2.0.0 SNAPSHOT builds with following code
ÿGetting 13 to 19 seconds in 1.8.10, whereas in 2.0.0SNAPSHOT builds 22 to 36 secondsÿ

			long t2 = ÿSystem.currentTimeMillis() ÿ;
			PrinterJob job = PrinterJob.getPrinterJob();
		 ÿ ÿjob.setPageable(new PDFPageable(pdDocument)); ÿ// ÿVersion 2.0.0 SNAPSHOT builds

ÿ


Do we haveÿ
Performance fix available in 2.0.0 SNAPSHOTS, if so please give full path and which build?
Is there a fix available where ÿAdmin privelage is not required?

Dear PDFBox Community

Adding Commits, John and Tilman in the mail request

Details are in below mail.

In brief again

In our system, PDF files generated in server and is sent to client and in client applet code
uses PDFBox to print.
With PDFBox 1.8.10, we have alignment issue as some characters were missing on left side.
With PDFBox 2.0.0-RC1, we have faced performance issue ( slow )

Do we have fix or patch availableÿ
either in 2.0.0-RC1 for performance ÿOR
alignment issue in 1.8.10
Our PDF documents uses True Type Fonts, mostly Ariel Unicode

Thanks a lot for your help and support.

Dear PDFBox Developers/Contributors

I am unable to subscribe to users mailing list as the link tries to open Outlook not the page
to subscribe, hence a seperate mail on similar/same issue discussed.

Issue:
-------ÿ
PDFBox2.0.0-RC1 is very slow in printinng ( taking 35 to 50 seconds ) ÿas it tries to load
fonts each time with the following message

WARNING: New fonts found, font cache will be re-built

WARNING: Building font cache, this may take a while
Nov 12, 2015 3:17:32 PM org.apache.pdfbox.pdmodel.font.FileSystemFontProvider saveCache
WARNING: Finished building font cache, found 522 fonts


Is the fix or patch available to avoid slow performance due to above ( rebuilding font cache
ÿevery tme ) ?ÿ
If the fix not available in 2.0.0-RC1,ÿIs there any way to fix alignment issue in PDFBox
1.8.10? as 1.8.10 left margin is too low and first few characters are found cut in printout.

With PDFBox1.8.10, there is no performance issue, but alignment in prontout is not proper.
ÿÿ
With PDFBox 2.0.0-RC1, we are facing performance issue.

PDFDocument used has Ariel ÿUnicode or True Type Fonts.ÿ

Similar discussion thread is pasted below, as I was unable to reply to same discussion thread,
nor able to subscribe to users mailing list, hence a seperate mail.

I guess that&#8217;s far from ideal?

The whole issue also happens on MacOSX. When you introduce this on-disk
cache a couple of months back, it worked fine, however one of the recent
changes to SVN must have wrecked the initially intended functionality. Not
only is the font caching setup 5-10 times as long as it used to be, it also
does not seem to persist it anymore. Version used:

This used to be anything between 1200ms and 2300ms and once it was
persisted onto disk, it was rather fast in subsequent calls. Unfortunately,
SVN does not provide the handy tool of "git bisect" to quickly find out
which change actually caused this regression.

There were only 4 changes since then, so it might be worth a try to just revert
that file.

(I can't help; for me, it has always been slow.)

Could it be that 1) you installed new stuff on your computer, 2) that MacOS has
many of its fonts in .ttc files? In Windows there are only 10.

on my OS X I have 92 ttc files (out of 384) :-)

Yep, OS X uses ttc much more heavily than Windows and some of those are big
Asian fonts which PDFBox parses relatively slowly.
