Problem with changing writing concern

[Luka Blažecki]

Hi

I am trying to change writing concern when creating connection : 

 var connPush = mongoose.createConnection(uri,{db:{fsync:false,j:false,w:0,wtimeout:10000}});

But when I test it results are same as when I set options to {db:{fsync:true,j:true,w:1,wtimeout:10000}}.

The results are around 500 inputs/second

When I changed connection driver to node-mongodb-native, it's working on 10000 input/second (when I set this options on top)

What I am doing wrong on setting this options ? 

I am using mongoose v3.3.1

So you're saying that mongoose is slower than the driver? If so, yes that is expected _but_ 500/sec vs 10000/sec seems extreme.

Please post the benchmark.

The options are set correctly. Depending on the benchmark, the bottleneck may be mongoose itself vs a slower write concern setting.

The problem is that I can't change write concern.

Can you post what is the correct way to change it (I want to disable write concern to write to journal and fsync)?

What does "doesn't work" mean? What do you expect to occur? What are you observing?

BTW latest mongoose is 3.5.11 and uses an updated driver. Please test with this version.

It's not that.

I found today that on Linux this command  

     var connPush = mongoose.createConnection(uri,{db:{fsync:false,j:false,w:0,wtimeout:10000}});

where uri is replica works but on Windows where uri is just one DB doesn't work.
