node.js - Performance comparison of websocket implementations -

-

edit: prevent closing question i'll narrow down essential.

can share performance test in mb/s between 2 websocket implementations listed below? application or hardware details irrelevant, 2 crude numbers simple common scenario suffice.

original question

did test performance of these 2 websocket implemetations node.js?

i couldn't find recent (just bunch of articles 2012-2013). see is:

  • overhead (if @ all, considering actual network latency more relevant guess both converge 0)
  • throughput (a simple mb/s figure same application/hardware great)
  • can ws broadcast data on network level (despite underlying tcp? @ possible?) or abused method name (which sends same message many clients in for() loop)?

even better:

  • comparison of with/without nagle's algorithm
  • comparison of json vs binary messages

edit: updated info newer, faster implementation

i integrate here nick newman's jun 17 '16 @ 20:08 comment avoid getting lost means.

a newer , faster implementation of websockets uws. promising results reported several devs. simple cases it's no-brainer. below discussion therefore superseded.

i wonder why nobody answer question. so, after more hours of search i've done before came page answers given.

i post here , answer own question others searching find easier.

the page benchmark comparison of ws. yes, it's pretty straightforward it's somehow buried away.

here relevant results:

in case want send 4-16kb json messages (even 4kb exaggeration, messages 100-200 characters). first graph shows 64kb there's no appreciable difference @ all. larger messages (around 16mb) becomes increasingly evident ws faster websocket-node.

for binary messages, both same (if not identical). makes me wonder if somehow borrowed code each other on github. nice btw both are on github shared , forked , on.

the following graphs show message fragmentation, relevant streaming, i'm not interested in. above answers question:

  1. performance identical non-fragmented text messages (up 16mb)
  2. performance identical non-fragmented binary messages (no size limit)

i'm using unity3d networked multiplayer online game have large complex 3d terrain scene forest, trees, cliff, hills, mountains, bounders, etc. players can build structures sort of minecraft, , put them anywhere in scene, or move them around anytime. aside human controlled players, there automated ai players , objects animals roaming around scene following path. the problem how make these automated ai players , animals, able navigate around static , dynamic player created structures, because path follow can blocked player created structures, or other players , other ai objects, cliffs etc. have find away around them or on track if tumble down off high cliff example. so made navmesh , used navagents, takes care of static, non moving objects, how make ai players navigate around each other , dynamic structures created players can number in hundreds? i thought of adding navmeshobstacle everything, result in being attached hundreds of objects since user created structures b...
