Since version 4.2.4 fonts are always embedded when creating .pdf files. This increases the size of the output files, and in our case, where we include thousands of .pdf files created by GLE into a huge LaTeX document, this has a remarkable impact on performance when scrolling through the final document. We suggest to make embedding the fonts an optional feature such that this can be switched on/off by the user.
Meanwhile we realised that it is not the embedded fonts that are increasing the size of the .pdf files. Instead (due to the new concept of layers?) the generation of the post script code produces much overhead. Would be great if there was a way to reduce this....
