That's brilliant! Looking at other threads, it's very confusing how much memory you ACTUALLY have (since some of these threads go back to the CORE). There is however an official link that [points to the memory output from the Web IDE](https://docs.particle.io/guide/getting-started/build/photon/#checking-code-memory-usage) and this claims that the Photon has:

> 110592 bytes for program  
> 20480 bytes for RAM

In my case it should mean that since I get this output from compile:

> text data bss dec hex filename  
> 107468 2124 12484 122076 1dcdc /workspace/target/workspace.elf

The text & data columns adds up to the amount of Flash used (out of 110592 available):  
`107468 + 2124 = 109592 (99% Flash used)`

The data + bss columns adds up to the amount of RAM used (out of 20480 available):  
` 2124 + 12484 = 14608 (71% RAM used)`

That would explain some interesting behavior in my app this week? 😊  
Time to start using that extra 1Mb of storage in the P1 modules!
