            sqlOptions.CommandTimeout(60);
            sqlOptions.EnableRetryOnFailure(
                maxRetryCount: 3,
                maxRetryDelay: TimeSpan.FromSeconds(5),
                errorNumbersToAdd: null);
        }));

    // Memory caching for frequently accessed data
    services.AddMemoryCache(options =>
    {
        options.SizeLimit = 100; // Limit cache size
        options.CompactionPercentage = 0.2;
    });

    // Response caching for static content
    services.AddResponseCaching(options =>
    {
        options.UseCaseSensitivePaths = false;
        options.MaximumBodySize = 1024 * 1024; // 1 MB
    });

    // Configure for Pakistani mobile users
    services.Configure<GzipCompressionProviderOptions>(options =>
        options.Level = CompressionLevel.Optimal);
}
