             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).
