Summary: Eliminate polling in runtime/transport/ring_buffer.c
Product: systemtap
Version: unspecified
Status: NEW
Severity: enhancement
Priority: P2
Component: runtime
AssignedTo: systemtap@sourceware.org
ReportedBy: wcohen@redhat.com
When a systemtap script is started the runtime transport ring buffer code
starts polling at 100 times a second. Even if a script has no output at all the
transport code still polls at 100 times a second. It would be nice particularly
for scripts that are doing system health monitoring, if the polling was removed
and the transport code only started when there was something to actually read
from the ring buffers.
