Re: Diazo performance problem

Dear Mauro,

I run it as bin/instance fg and bin/instance start.

I see that compiler runs every time in two cases and it is strage.
I tried to check differences between returned results 'compiled_doc' and
see that there is not any difference.

I know that compiler runs every time in DevelopmentMode but in my case it
runs over and over.

Best regards,
Bogdan.
