17:33:45 Bike 0.053s read 0.046s write on sbcl, so we're getting close to I/O speed limits. cool.

17:42:33 drmeister Excellent.

17:43:05 Bike let me just extend it for >8 byte and then i'll push

17:43:10 drmeister What does the sample code look like?

17:43:22 Bike the code i'm using to get times, you mean?

17:43:28 drmeister Yeah.

17:43:41 Bike really dumb. just (loop repeat 1000000 do (read-byte stream))

17:44:54 drmeister Ok - got it.

17:45:25 drmeister Regarding profiling. I learned that AMD has it's own profiling application.

17:45:41 drmeister https://developer.amd.com/amd-uprof/

17:46:36 drmeister It has a command line tool to gather data and a GUI for visualizing the data. It support Windows, Linux and FreeBSD.

17:47:19 drmeister It has flame charts but you need to use the GUI to generate them from the data the CLI tool gathers. AFAIK

17:50:31 Bike soudns useful though

17:51:27 drmeister It's probably why AMD perf support is weak - they put their energy into their own tool.

17:52:57 drmeister My problem with it is I have to get X-windows working on zeus to visualize flame graphs.

17:53:32 drmeister OR install Windows and use Linux subsystem for Windows to generate data and Windows to visualize it.

17:53:48 drmeister Windows virtual machine maybe.

17:54:12 drmeister Wait - no - that's still gonna require X-windows. Bleh.

21:53:48 Bike signed byte streams are screwing me up and i don't understand it

22:43:26 Bike don't know what's happening there. but they were broken already, so i just pushed the stuff to do unsigned I/O faster

23:28:51 Bike i cannot make read-byte return a negative integer. i do not understand.

0:01:32 Bike probably printf debugging time, but it's also a signedness problem so i have to make sure printf gets the right format string... eck...

4:43:26 Bike drmeister: does build still use LTO? i haven't been able to build clasp on my home system without my computer locking up, and there's a new bug report complaining about the same thing
