| Latency Comparison Numbers (~2012) | |
| ---------------------------------- | |
| L1 cache reference 0.5 ns | |
| Branch mispredict 5 ns | |
| L2 cache reference 7 ns 14x L1 cache | |
| Mutex lock/unlock 25 ns | |
| Main memory reference 100 ns 20x L2 cache, 200x L1 cache | |
| Compress 1K bytes with Zippy 3,000 ns 3 us | |
| Send 1K bytes over 1 Gbps network 10,000 ns 10 us | |
| Read 4K randomly from SSD* 150,000 ns 150 us ~1GB/sec SSD |
| eXtreme Go Horse (XGH) Process | |

| 1. I think therefore it's not XGH. | |
| In XGH you don't think, you do the first thing that comes to your mind. There's not a second option as the first one is faster. | |
| 2. There are 3 ways of solving a problem: the right way, the wrong way and the XGH way which is exactly like the wrong one but faster. | |
| XGH is faster than any development process you know (see Axiom 14). |
One of the best ways to investigate a problematic Xamarin.Android Binding is to first ensure you have the proper tooling available:
| namespace Website.TagHelpers | |
| { | |
| using System.Security.Claims; | |
| using System.Text; | |
| using System.Text.Encodings.Web; | |
| using Microsoft.AspNetCore.Mvc.Rendering; | |
| using Microsoft.AspNetCore.Mvc.ViewFeatures; | |
| using Microsoft.AspNetCore.Razor.TagHelpers; | |
| using Microsoft.Extensions.Options; |
| public class CountTruesBenchmarks | |
| { | |
| private readonly bool[] boolArray; | |
| public CountTruesBenchmarks() | |
| { | |
| var rnd = new Random(42); | |
| boolArray = Enumerable.Range(0, 500).Select(_ => rnd.NextBoolean()).ToArray(); | |
| } |

| using System.IO.Compression; | |
| using System.Linq; | |
| using System.Net.Http; | |
