Discussion list for thrulay, a network testing tool

[Csaba Kiraly <>]

Hi,

First of all, thanks for thrulay, the only tool I've found that measures
application level RTT, i.e. something useful when TCP level proxying is
part of the system!

I've made a small patch that changes the size of the data block returned
from the server to the client. The option was already there in the code
as a compile time constant, it becomes a configurable parameter after
you apply the patch. Why is it useful:
- better control over what do you measure
- you can regulate the ratio of client->server and server->client traffic

How it was before:
-l parameter defines the block size sent from the client to the server.
Default is 64 Kilobytes. It is enough to define it in the client.
- after a block is received by the server, the first 16 bytes (the
timestamp) is returned to the client.

After the patch:
-l works as before
-r defines the size of the return block (I think it works only up to the
amount of -l, in which case all the traffic is looped back to the
client). Currently, -r should be specified at both sides, both when
starting the client and when starting the server.

Hope someone finds it useful
Csaba
