How big is the SAVFL definition size ?

Hi people,

I'm not sure if this is the issue of my long outstanding failed LUA server or this is just the normal SAVFL client update 1.9 GB in size ?

I have just made my LUA server v2.3.2 working to download the updates from the internet since many moons ago, I saw that the update size was 1.9 GB, but then I was very surprised and confused since the size of the definition is 1.9 GB pushed to the SAVFL client ?

why the size is so big ?
