>             Project: PDFBox
>          Issue Type: Improvement
>          Components: PDModel
>    Affects Versions: 2.0.0
>         Environment: MS Windows Systems with low RAM < 3GB and number of =
fonts were less < 592 (or if desired fonts in PDF to be printed are not ava=
ilable in local system )=20

>             Fix For: 2.0.0

>
> PDFBox 2.0.0-RC1, SNAPSHOTS and RC2 versions print takes 15+ seconds.
> Steps to reproduce
> --------------------------=20
> Use Windows System with < 3 GB RAM
> Use Systems with less number of fonts or without specific fonts in PDF fi=
le  to be printed.
> Printing PDF file=20
> Took 14 to 20 seconds in system with 3 GB RAM which had 522 foints
> Took 24 to 34 seconds in system with 2 GB RAM which had 90 fonts
> Took only 2.5 seconds in system with 8 GB RAM which had 1025 fonts.=20
> Doubt
> --------=20
> Not browsed the code, but following is the doubt as causing performance i=
ssue.
> Though the code caches fonts by storing fonts in local .pdfbox.cache file=
 first time and caching fonts for subsequent times.
> Not clear whether the code updates the pdfbox fonts cache file if new fon=
ts are found in new PDF file to be printed, while printing subsequent times=
.=20
> If the fonts in PDF file to be printed is not available in the .pdfbox.ca=
che file stored in local system/local system what is the behaviour?  Will t=
he code download fonts and update cache for subsequent times or is it limit=
ed by fonts available in local system?  Looks like later is the case and pe=
rformance got hit either due to RAM or not constantly updating fonts cache =
or due to un availability of fonts in local system.
