a mgo session pool still need more work...
go get gopkg.in/mgo.v2
go get github.com/JodeZer/mgop
with mgo, client hosts may create too much connections by using Copy method in high concurrency situation,like this
func foo(){
s := globalSession.Copy()
defer s.Close()
}especially when using mgo.Eventual mode.
mgop helps mongo doing better in high concurrency situation by buffering some sockets and tranporting requests through these sockets.
func foo(){
p, _ := mgop.DialPool("127.0.0.1:27017", 5)
session := p.AcquireSession()
defer session.Release()
session.DB("test").C("test").Insert(bson.M{"id":1})
