+## Sweep Test Settings
+#
+# Common assumptions for sweep delay test:
+# The system should be able to handle CAS workload at any delay.
+# Using eBPF, we find that Nginx lockref inter-arrival delay is less than 32us,
+# and lockref_get to lockref_put_return delay is less than 2us. Therefore we
+# create this script to sweep <32us delay using -p parameter and keep -c
+# parameter at 1us because eBPF intrinsic overhead is about 1us. We also find
+# the ratio between -c and -p is relatively fixed, e.g. 1:8 ~ 1:16. We choose
+# 1:9 for the last case (-c=3000ns, -p=28000ns).
