Hello,
I'm looking for a description of the parameters prefixed with
proxy.config.exec_thread in records.config to help us better tune for
performance. I looked over the admin docs and prior user group posts and
haven't found any clear descriptions, although it is possible I just
missed it.
CONFIG proxy.config.exec_thread.autoconfig INT 1
CONFIG proxy.config.exec_thread.autoconfig.scale FLOAT 1.500000
CONFIG proxy.config.exec_thread.limit INT 2
If autoconfig is enabled ("1"), then you will get 1.5 worker thread
(net-thread) per core. If a core is a hyperthread core, it only counts as
1/4 of a core. If autoconfig is disabled ("0"), then exec_thread.limit is
used, and you manually control the number of threads.
Some example (with default settings):
Dual Core, no HT: 3 worker threads
Quad Core, with HT: 4 * 1.5 + 4 * 0.25 * 1.5 == 7
