I am running an application how reads and write a batch process using MongoDb in 2 identical machines. One running Windows 8.1 and the other running Windows Server 2012.
The MongoDb performance in the Windows Server 2012 machine is 5 times worse than Windows 8.
Both machines have 16Gb of RAM, but the mongod.exe process consumes 1.2Gb RAM in Windows 8 and 500Mb in Windows server in an identical local database.
I already use MongoDb 2.4, 2.6 and 2.6 legacy and de behavior is the same.
Has anyone seen this behavior before?
