Maybe you remember the problems we had with a custom page in Japan loading it from TRIUMF. It took almost one minute since each RPC request took
about 1s round-trip. This got fixed by the modb* scheme where the framework actually collects all ODB variables in a custom page and puts them
into ONE rpc request (making the path an actual array of paths). That reduced the requests from 100 to 1 in the above example. Maybe the same

Looks like a localisation issue. Your floats are formatted as "6,6584e+01", whereas the JSON decoder expects "6.6584e+01".

This should be fixed in the latest commit to the midas develop branch. The JSON specification requires a dot for the decimal separator, so we must ignore |

my vote is to bump the ODB size limit to 1999*1000*1000 (not quite 2GB). but this needs to be tested. especially save and restore from ODB, XML and JSON
files, including how long it takes to save and load a 1.9GB ODB. K.O. |

At the run start mlogger writes the ODB to the .mid file. This needs conversion (binary ODB -> XML ASCII) which can take time.

I agree with you, option 2 is better and works well.
The only problem is that if you are showing multiple histograms in the same window the keyDown even will affect all of the histories in the window.
This may be the intended behaviour, but I think that if we can find a way to have the event affecting only the intended history (focused element for example) |
