Question

Raven.Server started and binded to port 8022. I initialize DataStore in the following way:

        var store = new DocumentStore() { Url = "http://localhost:8022" };
        store.Initialize();

Then i’m making such query:

        using (var session = store.OpenSession())
        {
            Stopwatch watch = new Stopwatch();
            watch.Start();

            var result = session.LuceneQuery<Item>("Raven/DocumentsByEntityName")
                .WhereEquals("Tag", "Items")
                .ToList();

            watch.Stop(); // watch.ElapsedMilliseconds == ~550 ms

            return result;

        }

And watch.ElapsedMilliseconds is always ~550 ms.
But when i look to RavenDB console i see that query was processed in 3 ms:

Request # 170: GET     -    3 ms - 200 - /indexes/Raven/DocumentsByEntityName?query=Tag%253A%255B%255BItems%255D%255D&start=0&pageSize=128

Thus ~ 99.5% of time have been spent not in RavenDB. What is the problem? (RavenDB 147)

When i switch to self-hosting of RavenDB (i.e. as embedded client) everything is okay (~3ms).

To clarify that issue not in network, http debuggers, dns servers etc. i also tested this:

            Stopwatch watch = new Stopwatch();
            watch.Start();

            WebClient client = new WebClient();
            var result = client.DownloadString("http://127.0.0.1:8022/indexes/Raven/DocumentsByEntityName?query=Tag%253A%255B%255BItems%255D%255D&start=0&pageSize=128");

            watch.Stop(); // watch.ElapsedMilliseconds == ~3-10ms

Fast. But switching to Raven.Client.Lightweight increase response time in 200 times (550-600 ms)

Answer 1

Problem was because of middleman on my computer – NOD32. If you are also using it – uncheck the following checkbox:

Setup -> Advanced setup -> Antivirus and antispyware -> Protocol filtering -> “Enable application protocal content filtering”

Simple disabling of antivirus or firewall doesn’t help!
