Timeout issue #13
Description
Hi,
I have some issues with this library and the number of connections it creates. I don't know exactly if the library is the problem or my configs but I was doing a simple test with
{
maxSockets: 5,
maxFreeSockets: 5,
keepAliveMsecs: 100
.....
}
then do 100 requests with some small random time intervals between them. The result i get is something like this and doesn't seem to add up
{
.....
keepAliveMsecs: 100,
keepAlive: true,
maxSockets: 5,
maxFreeSockets: 5,
maxKeepAliveRequests: 0,
createSocketCount: 18,
timeoutSocketCount: 4,
requestFinishedCount: 100
}
If only 4 sockets timed out why did it create 18 ? Shouldn't have been 9 there ? The initial 5 sockets and the additional 4 that were replaced because they timed out. Btw, the numbers vary on every run. What am I missing here ?

keepAliveMsecs:100 meaning a free socket not active for 100ms it will close.

Yes, unless there is activity on it so it doesn't time out. So only 4 sockets timed out, and if they needed to be recreated, a maxim of 9 sockets should have been created in total, or anywhere between 5 and 9 if some of those 4 timed out sockets expired and the end of the test and had nothing left in queue. So why 18 ?

can you show me the
closeSocketCountandrequestCountvalues?cthackers commentedon Feb 2, 2015
I don't have such values in the result. I use version 0.2.3.

also i get an error like this
(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.
the stack trace indicates _http_agent.js:214:10 and agent.js:107:20

and for HTTPS connections, it uses the certificate files as keys in the getName function. The application i use this in, has one 50KB certificate file with all the certificates. The log increased to 1.5 GB in less than a minute. Why in the world you would use the content of the certificates and keys as the key to the map ?

can you show me your demo codes, node version and agentkeepalive version, I want to repeat what your meaning.

I too would like to run this library through some perf tests. I know this thread is a little stale, but @fengmk2 can you post the scripts, versions, etc you used for testing?
