Currently, flow-perf measures the performance of
rule installation/deletion operations by breaking
down the entire number of operations into windows
of fixed size (i.e., 100000 operations per window).
Then, flow-perf measures the total time per window
and computes an average time across all windows.

This commit allows flow-perf users to configure
the number of rules per window instead of using
a fixed pre-compiled value. To do so, users must
pass --rules-batch=N, where N is the number of
rules per window (or batch).
For consistency reasons, flow_count variable is
now renamed to rules_count. This variable is the
total number of rules to be installed/deleted.

For example, if a user wants to measure how much
time it takes to install 1M rules in a certain NIC,
he/she can input:
--rules-count=1000000
This way flow-perf will break down 1M flow rules into
10 batches of 100k flow rules each (this is the default
batch size) and compute an average across the 10
measurements.
Now, if the user modifies the number of rules per
batch as follows:
--rules-count=1000000 --rules-batch=500000
then flow-perf will break down 1M flow rules into
2 batches of 500k flow rules each and compute the
average across the 2 measurements.

Finally, this commit also adds default variables
to the usage function instead of hardcoded values.

Hi,

Any news on this patch?
Is there anything else I could do?

Thanks,
Georgios

Hi,

Any news on this patch?
Is there anything else I could do?

Hi,

Is what you are asking possible with a simple git commit --amend?

I think Thomas can add it if he want to merge it in this version.

Moreover I think you need to keep the ack between versions and the person who acked before should comment if newer version not ok with him, otherwise he is ok with it. “Using git commit —amend”.

Thomas, correct me if I’m wrong, At least this how I understood the procedure here.

Moreover I noticed that you sending the versions as new patch all the time, but for history and comments tracking you should send with versions. V2-v3 ...etc with reply to older version of the patch.

BRs,

You missed updating the file doc/guides/tools/flow-perf.rst
