While working in the ESS app searching for tag=attack last 60 mins time range I get about 1,262 events. I get two warning banners.
1. Field extractor name=autoheader_for_sav is unusually slow (average execution time=721ms, probes=10 warning max=500ms)
2. Field extractor name=auto_kv_for_mcafee_ids_message is unusually slow (average execution time=541ms, probes=10 warning max=500ms)
What can I tune to avoid these warnings?

The solutions are : - identify and improve the regexes/field extractions ( if possible ) - or change the warning threshold for key values extraction

edit $SPLUNK_HOME/etc/system/local/limits.conf, and change max_extractor_time value see http://docs.splunk.com/Documentation/Splunk/latest/Admin/Limitsconf

[kv]
max_extractor_time = <integer>
# Maximum amount of CPU time, in milliseconds, that a key-value pair extractor will be allowed to  take before warning. If the extractor exceeds this execution time on any event a warning will be issued  Defaults to 1000

avg_extractor_time = <integer>
# Maximum amount of CPU time, in milliseconds, that the average (over search results) execution time of   a key-value pair extractor will be allowed to take before warning. Once the average becomes larger  than this amount of time a warning will be issued Defaults to 500
