Summary: Performance regression since PDFRenderer
Key: PDFBOX-2007
URL: https://issues.apache.org/jira/browse/PDFBOX-2007
Project: PDFBox
Issue Type: Bug
Components: Rendering
Affects Versions: 2.0.0
Reporter: François Bernier
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 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
I have not looked any further than this and have no more data to give you (yet).
