A simple CPU profiler for AmigaOS 4

Tequila

Tequila is a simple CPU profiler which samples current running tasks.

Command-line parameters / icon tooltypes

SAMPLES [99, 10000] - how often running task is sampled (Hz). Default is 5000.

INTERVAL [1, 5] - display update interval (seconds). Default is 1.

DEBUG - some additional logging.

PROFILE - try to collect symbol data. Note: it doesn't work properly yet.

GUI - start in window mode.

CUSTOMRENDERING - display task list without using listbrowser.gadget. It's faster than listbrowser.gadget, so Tequila uses less CPU in this mode.

FAQ

Q) Is it compatible with CPU dockies, CPU Watcher and similar?

A) Should be, Tequila doesn't busyloop or spawn any "idler" tasks.

Q) idle.task is spending all my CPU!

A) Yes, that's normal when system is idling, when there are no more important tasks running.
