But just compare yourselt... time ubus call rc list time ubus call luci getInitList The difference is quite drammatic... This series just allign the rc feature to the luci one and it's really not bloating, just adding feature... The added option are all optional. -- Ansuel ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

Can I ask what you're doing that you are calling ubus service list so often that 70ms vs 5ms is meaningful? You're complicating APIs and adding code for what seems wildly unnecessary?

[rpcd PATCH 3/4] rc: add option to skip running check for list method
Running check may be slow and increase result time in the other of 70ms
for the list method.
Add an option to skip running check by passing the skip_running_check as
true in the list method args to speedup execution if the running info is
not needed.
With the option set to true the execution time lower to just 5ms.
