title: Error: Timeout performing GET using Redis
body: <p>I have a list of 200,000+ users in Redis cache. </p>
  
  <p>When I try to fetch that list from Redis cache using <code>StackExchange.Redis StringGet</code> I get <code>TimeOut</code> error:</p>
  
  <blockquote>
    <p>"Timeout performing GET , inst: 1, mgr: ExecuteSelect, err: never, queue: 2, qu: 0, qs: 2, qc: 0, wr: 0, wq: 0, in: 8596, ar: 0, IOCP: (Busy=0,Free=1000,Min=2,Max=1000), WORKER: (Busy=0,Free=4095,Min=2,Max=4095), clientName: WIN-XYZ"</p>
  </blockquote>
  
  <p>Can someone explain what does these values signifies: Busy, Free, Min and Max?</p>
  
  <p>I have already increased the timeout to much larger extent via this in constructor:</p>
  
  <pre><code>redis = ConnectionMultiplexer.Connect(string.Format("{0},allowAdmin=true,connectTimeout=1500000,keepAlive=100", redisConfig));
  </code></pre>
  
  <p>But I am still getting the timeout every time I fetch the list of users.</p>
  
  <p>This is not the problem with GET only I am getting issues while setting that list too:</p>
  
  <blockquote>
    <p>Timeout performing PSETEX , inst: 1, mgr: ExecuteSelect, err:
    never, queue: 2, qu: 0, qs: 2, qc: 0, wr: 1, wq: 1, in: 0, ar: 0,
    IOCP: (Busy=0,Free=1000,Min=2,Max=1000), WORKER:

  <p>at:</p>
  
  <pre><code>db.StringSet(cacheKey, bytes, slidingExpiration);
  </code></pre>
  
  <p>I even tried raising the various timeouts mentioned here <a href="https://stackexchange.github.io/StackExchange.Redis/Configuration" rel="noreferrer">https://stackexchange.github.io/StackExchange.Redis/Configuration</a>:</p>
  
  <pre><code>                redis = ConnectionMultiplexer.Connect(string.Format("{0},allowAdmin=true,syncTimeout=600000,connectRetry=3,connectTimeout=600000,keepAlive=180", redisConfig));
                  redis.PreserveAsyncOrder = false;
  </code></pre>
  
  <p>but I am still getting the following error:</p>
  
  <blockquote>
    <p>Timeout performing GET , inst: 0, mgr: ExecuteSelect, err: never,
    queue: 0, qu: 0, qs: 0, qc: 0, wr: 0, wq: 0, in: 0, ar: 0, IOCP:
