Background System processing lots of files - lots of shared data Processing could happen in parallel - saving to disk could not Using SpinLock for sync - is default for engine code - doesn't do system call Job ◼ : Saving Job (Waiting) ◼ : Saving Job (Writing) ◼ : CPU Usage 37Profiler captures of simulated example • Yellow - ordinary jobs - capped at 50% CPU • Red - ordinary jobs part of saving - capped capped at 50% • Teal - saving jobs Easier to see here - I've made regular jobs use 50% CPU 100% usage is SpinLocks - Followed by 20% usage in saving jobs Speaker notes38Speaker notesAVOID BLOCKING – CONFIRMATION

The Footprint Editor provides many time saving tools such as: Fast pad numbering by simply dragging the mouse over pads in the order you want them optionally provides "Copy-On-Write" (COW) support for editing footprints read from the GitHub repo and saving them locally. Therefore the "GitHub" plugin is for read-only for accessing remote pretty footprint access to the files (loading and saving), configuration options, printing, plotting and the help files. 3.9.1.

The Entity is then persisted using the ArticlesTable we created earlier. After saving our new article we use FlashComponent’s success() method to set a message into the session. The success ?> which displays flash mes- sages and clears the corresponding session variable. Finally, after saving is complete, we use Cake\Controller\ Controller::redirect to send the user back to the articles list
