rm contrib/perftest
Perftest was intended to be used for testing CPU intensive tasks of Podman. However, it does not compile for a long while and is not integrated in the CI which clearly indicates that it has not been used for a considerable amount of time. Remove contrib/perftest entirely. If the desire arises to revive it, all code is still reachable in the git history. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

## perftest : tool for benchmarking and profiling libpod library
|
||||
perftest uses libpod as golang library and perform stress test and profile for CPU usage.
|
||||
|
||||
Build:
|
||||
|
||||
```
|
||||
# cd $GOPATH/src/github.com/containers/libpod/contrib/perftest
|
||||
# go build
|
||||
# go install
|
||||
```
|
||||
|
||||
Usage:
|
||||
|
||||
```
|
||||
# perftest -h
|
||||
Usage of perftest:
|
||||
|
||||
-count int
|
||||
count of loop counter for test (default 50)
|
||||
-image string
|
||||
image-name to be used for test (default "docker.io/library/alpine:latest")
|
||||
|
||||
```
|
||||
|
||||
e.g.
|
||||
|
||||
```
|
||||
# perftest
|
||||
runc version spec: 1.0.1-dev

|

Simple profiling support package for Go
|
||||
|
||||
[](https://travis-ci.org/pkg/profile) [](http://godoc.org/github.com/pkg/profile)
|
||||
|
||||
|
||||
installation
|
||||
------------
|
||||
|
||||
go get github.com/pkg/profile
|
||||
|
||||
usage
|
||||
-----
|
||||
|
||||
Enabling profiling in your application is as simple as one line at the top of your main function
|
||||
|
||||
```go
|
||||
import "github.com/pkg/profile"
|
||||
|
||||
func main() {
|
||||
defer profile.Start().Stop()
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
options
|
||||
-------
|
||||
|
||||
What to profile is controlled by config value passed to profile.Start.
|
||||
By default CPU profiling is enabled.
|
||||
|
||||
```go
|
||||
import "github.com/pkg/profile"
|
||||
|
||||
func main() {
|
||||
// p.Stop() must be called before the program exits to
|
||||
// ensure profiling information is written to disk.
|
||||
p := profile.Start(profile.MemProfile, profile.ProfilePath("."), profile.NoShutdownHook)
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
Several convenience package level values are provided for cpu, memory, and block (contention) profiling.
|
||||
|
||||
For more complex options, consult the [documentation](http://godoc.org/github.com/pkg/profile).
