Chronon Performance
How much log does it output and what's the typical runtime cost of running with chronon switched on in my application.

The performance of Chronon is described in more detail here and here.
Chronon performance and the size of the log files is measured by
the amount of time spent in the execution of recorded code
You an have a 1 million line j2ee program which spends most of its time doing IO and it wont generate much of a log.
On the other hand you can have a small 10 line program with a super tight loop, which can generate a large log in seconds.
Since the size of log files and the performance impact varies so greatly depending on the nature of the program, the duration it is run for, and the hardware it is run on, we do not give out raw performance numbers from our side. Also since the current beta is not meant to be run in production scenratios, benchmark numbers are not a priority for us.
We have released a beta version so that you can try out the performance yourself and tell us what you think of it.

"On the other hand you can have a small 10 line program with a super tight loop, which can generate a large log in seconds."
If small 10 line program only performs computation, isn't it sufficient to only record input parameters and snaphots at some regular intervals to the log? All other state can be computed from this info.-
There are many, many technical issues associated with that design, especially in a larger program with multiple threads and external IO.
It is an architecture we may look at in the future but we dont do that right now. -
