+## Оптимизация сети
+
+### 1. Connection Pooling
+```java
+// Оптимизация HTTP соединений
+@Configuration
+public class HttpClientConfig {
+    @Bean
+    public RestTemplate restTemplate() {
+        HttpComponentsClientHttpRequestFactory factory = 
+            new HttpComponentsClientHttpRequestFactory();
+        
+        // Настройка пула соединений
+        PoolingHttpClientConnectionManager connectionManager = 
+            new PoolingHttpClientConnectionManager();
+        connectionManager.setMaxTotal(100);
+        connectionManager.setDefaultMaxPerRoute(20);
+        
+        CloseableHttpClient httpClient = HttpClients.custom()
+            .setConnectionManager(connectionManager)
+            .setDefaultRequestConfig(RequestConfig.custom()
+                .setConnectTimeout(5000)
+                .setSocketTimeout(10000)
+                .build())
+            .build();
+        
+        factory.setHttpClient(httpClient);
+        return new RestTemplate(factory);
+    }
+}
+```
+
+### 2. Compression
+```java
+// Сжатие HTTP ответов
+@Configuration
+public class CompressionConfig {
+    @Bean
+    public FilterRegistrationBean<CompressionFilter> compressionFilter() {
+        FilterRegistrationBean<CompressionFilter> registration = 
+            new FilterRegistrationBean<>();
+        registration.setFilter(new CompressionFilter());
+        registration.addUrlPatterns("/*");
+        registration.setName("compressionFilter");
+        registration.setOrder(1);
+        return registration;
+    }
+}
+
+@Component
+public class CompressionFilter implements Filter {
+    @Override
+    public void doFilter(ServletRequest request, ServletResponse response, 
+                        FilterChain chain) throws IOException, ServletException {
+        
+        HttpServletRequest httpRequest = (HttpServletRequest) request;
+        HttpServletResponse httpResponse = (HttpServletResponse) response;
+        
+        String acceptEncoding = httpRequest.getHeader("Accept-Encoding");
+        if (acceptEncoding != null && acceptEncoding.contains("gzip")) {
+            httpResponse.setHeader("Content-Encoding", "gzip");
+            GzipResponseWrapper gzipResponse = new GzipResponseWrapper(httpResponse);
+            chain.doFilter(request, gzipResponse);
+            gzipResponse.finish();
+        } else {
+            chain.doFilter(request, response);
+        }
+    }
+}
+```
+
+### 3. CDN Integration
+```java
+// Интеграция с CDN
+@Service
+public class CDNService {
+    @Value("${cdn.base-url}")
+    private String cdnBaseUrl;
+    
+    public String getCDNUrl(String path) {
+        return cdnBaseUrl + "/" + path;
+    }
+    
+    public void uploadToCDN(String path, byte[] content) {
+        // Загрузка контента в CDN
+        // Реализация зависит от выбранного CDN провайдера
+    }
+    
+    public void invalidateCDNCache(String path) {
+        // Инвалидация кэша CDN
+        // Реализация зависит от выбранного CDN провайдера
+    }
+}
+```
