ASP.NET Core 2.2 Kestrel 服务器的性能问题可能有多种原因。下面是一些可能的解决方法及相关代码示例:
调整服务器配置:
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseKestrel(options =>
{
options.Listen(IPAddress.Any, 5000);
options.Limits.MaxConcurrentConnections = 100;
options.Limits.MaxConcurrentUpgradedConnections = 100;
options.Limits.MaxRequestBodySize = 10 * 1024;
options.Limits.MinRequestBodyDataRate =
new MinDataRate(bytesPerSecond: 100, gracePeriod: TimeSpan.FromSeconds(10));
options.Limits.MinResponseDataRate =
new MinDataRate(bytesPerSecond: 100, gracePeriod: TimeSpan.FromSeconds(10));
options.Limits.KeepAliveTimeout = TimeSpan.FromMinutes(2);
options.Limits.RequestHeadersTimeout = TimeSpan.FromMinutes(1);
})
.UseStartup();
public void ConfigureServices(IServiceCollection services)
{
services.AddResponseCompression(options =>
{
options.EnableForHttps = true;
});
// ...
}
优化数据库访问:
public async Task Index()
{
var data = await _dbContext.MyTable.ToListAsync();
return View(data);
}
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext(options =>
{
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
options.UseConnectionPooling();
});
// ...
}
缓存常用数据:
public IActionResult Index()
{
var data = _cache.GetOrCreate("myKey", entry =>
{
entry.SlidingExpiration = TimeSpan.FromMinutes(10);
return _dbContext.MyTable.ToList();
});
return View(data);
}
使用异步 IO:
public async Task Index()
{
var data = await SomeAsyncOperation();
return View(data);
}
使用分布式缓存:
public void ConfigureServices(IServiceCollection services)
{
services.AddDistributedRedisCache(options =>
{
options.Configuration = "localhost";
options.InstanceName = "MyInstance";
});
// ...
}
需要注意的是,解决性能问题的方法可能因具体情况而异,需要结合实际场景进行调整和优化。以上提供的解决方法仅供参考。
