PDFSharp/Migradoc PDF 3k +行の生成が極端に遅い

Question

私は約3,500のレコードでPDFを生成しようとしています。それはほぼ5-10分かかります。それは文字通りばかげている。私はここに何かを逃していますかそれはRenderDocument()メソッドに固執しています。私はMigraDoc.Rendering.dllのバージョン1.32を使用しています。PdfSharp.dll

ここに私のコードのスニペットがあります。私はPDFを構築する方法で最適化できるものがありますか？このコードで生成した他のPDF約50個のレコードが即座に作成されます。

だから、どちらかそれより良いイマイチようにもPDFシャープ1.5ベータ版はまだベータ版であり、それは文字通り非常に遅いレンダリング大規模なデータセットであることが判明します。私は、サードパーティのパッチソリューションをつかむために持っていた：

Answer 2

まずは、PDFsharp 1.50 beta 3bを試してみてください。はるかに高速です。
