* Remove hardcoded buffer of 1 from latency test on server and client(#1)
* Remove hardcoded buffer of 1 from latency test on server and client
* Default latency test (#2)
* Default latency test so we dont introduce regression
* Fixed /proc/net/snmp parsing bug
* Fixed a bug when parsing /proc/net/snmp for Linux machines
* Removed unused, commented code
* Changed error messages to Go best practices (wrapping-friendly)
* * Upgrade Dockerfile
* Upgrade to Go 1.13
* Refactor the command line plotting & management code into a package
* Refactor the stats-gathering code into a new package
* Switch to build flags for non-portable packages/code
Once a tag is created on the repository, a new build would be produced
and automatically released on github. The version of the build is also
set automatically in the binary using -ldflags option.
Initial version of -r for TCP bandwidth tests + few other enhancements:
- Add timestamp in log messages.
- Handle the case where timer tick is delayed on client side. Server side still
needs work.
- Use high value of GOMAXPROCS to fix starvation of some goroutines.
- Support option to disable per connection statistics. If large number
of sessions are used, then per connection stats were making it hard
to read the results on console.
- Synchronize stats timer between client/server. This makes server and
client print similar test results. Earlier, under varying TCP throuhgput,
results in server and client side were different due to different time
periods for calculating throughput.
* Fix command line arguments to enable supporting external server mode.
* Initial version of external mode server. This can work behind a load
balancer.
* Intermediate changes for xserver/xclient.
* Few fixes for external mode. Add support for 'g' for gap in connection
latency test.
Initial version of HTTPS support. This uses a dynamically generated self-signed certificate. The main use case is to measure performance of middle boxes like firewalls and proxies.
WSL does not seem to have /proc/net/snmp. Convering this error to debug
message since there is nothing actionable on this. This only impacts UI
functionality cosmetically as UI won't be able to display TCP retransmit
count.
Initial version of TCP ping.
This needs enhancements listed below, but is a workable solution (for now):
- Better goroutine synchronization for exit tracking
- Code cleanup for handling of warmup run
- Support for custom number of warmup connections
- Support for custom sleep between successive connections
- Option to select -4 or -6 to force IP version
- Logging the results in json format
