------------------------------------------------------------------
I attached the PDF used in the posted benchmark. If I remember correctly when I
last tested, pretty much every PDFs were slower but this one was way worse. I
am sorry for the late reply I am quite busy lately. I may eventually try
profiling deeper later.
I would appreciate if you download the PDF and tell me when you all have it so
I can remove it. I don't care too much but there is an email into it... the PDF
is about a book which will finally never be published to I don't think it's a
problem.

> Hi,
> I have the following toy project where I use PDFBox:
> https://github.com/fbernier/taz-clj
> I've been using the snapshot versions of PDFBox for quite a while and
> recently since the move from RenderUtil#convertToImage to
> PDFRenderer#renderImage (this commit:
> https://github.com/fbernier/taz-clj/commit/47917d494f2a9a0999da7f36827c45145d4bb42c),
> there is quite a big performance regression. If I change the PDFBox
> dependency to 1.8.x, everything is good. Here are my benchmarks:
> PDFBox 1.8.x:
> Running 1m test @ http://127.0.0.1:8080/testing.pdf?page=1
> 4 threads and 4 connections
> Thread Stats Avg Stdev Max +/- Stdev
> Latency 208.98ms 58.27ms 391.43ms 52.08%
> Req/Sec 4.63 1.73 8.00 62.88%
> 1224 requests in 1.00m, 72.34MB read
> Requests/sec: 20.40
> Transfer/sec: 1.21MB
> PDFBox 2.0.0:
> Running 1m test @ http://127.0.0.1:8080/testing.pdf?page=1
> 4 threads and 4 connections
> Thread Stats Avg Stdev Max +/- Stdev
> Latency 920.25ms 378.94ms 2.76s 91.38%
> Req/Sec 0.80 0.40 1.00 80.17%
> 275 requests in 1.00m, 15.85MB read
> Requests/sec: 4.58
> Transfer/sec: 270.41KB
> I have not looked any further than this and have no more data to give you
> (yet).
