async/await
,避免线程池饥饿。[HttpGet] public async Task<IActionResult> GetProducts() { var products = await _context.Products.AsNoTracking().ToListAsync(); // EF Core异步查询 return Ok(products); }
services.AddResponseCompression(options => { options.EnableForHttps = true; options.Providers.Add<GzipCompressionProvider>(); });
混合缓存架构:
public class ProductRepository { private readonly IMemoryCache _memoryCache; private readonly IDatabase _redis; public async Task<List<Product>> GetProductsAsync() { const string cacheKey = "products"; if (_memoryCache.TryGetValue(cacheKey, out List<Product> products)) return products; // Redis缓存检查 var cachedProducts = await _redis.StringGetAsync(cacheKey); if (!string.IsNullOrEmpty(cachedProducts)) { products = JsonConvert.DeserializeObject<List<Product>>(cachedProducts); _memoryCache.Set(cacheKey, products, TimeSpan.FromMinutes(10)); return products; } // 数据库查询并同步缓存 products = await _context.Products.ToListAsync(); _memoryCache.Set(cacheKey, products, TimeSpan.FromMinutes(10)); await _redis.StringSetAsync(cacheKey, JsonConvert.SerializeObject(products), TimeSpan.FromMinutes(10)); return products; } }

Docker部署:

http { upstream backend { server server1:5000; server server2:5000; } server { location / { proxy_pass http://backend; } } }
硬件冗余:双电源+RAID10磁盘阵列,故障恢复时间压缩至秒级。
