title: Generate a business letter for 100+ leads using wkhtmltopdf
body: <p>We need to print Business Letter for a given list with mail merge facilities.</p>
  <p>My client is not willing to spend $$ on a paid ASP.NET control to make PDF. So I opted in for WKHTMLtoPDF and it works fine for us until one day the client tried to get a PDF of 100+ leads, resulting in complete failure of PDF generation. It works just fine with a 10-20 page PDF, but not for 100.</p>
  <p>Are there any tips &amp; tricks to improve performance? We are using Cloud-hosted IIS 7 with ASP.NET 4 if that matters.</p>
