In many cases this approach improves the overall processing speed, and indirectly makes for a more scalable site.<\/p>\n<p>However, buffering has two minor defects:<\/p>\n<ol>\n<li>The end user might perceive a loss in speed, because she won&#8217;t see any output until the page is complete, and<\/li>\n<li>Buffered output has to be maintained on the server, therefore your ASP application is going to take more memory than it would do if buffering were disabled. On server machines with an inadequate amount of memory, large HTML pages can reduce the overall performance.<\/li>\n<\/ol>\n<p><!--more--><\/p>\n<p>Fortunately, you can solve both problems with judicious use of the <strong>Response.Flush<\/strong> method, that lets you flush the output buffer periodically when sending a large amount of data back to the client. For example, if you are sending back to the client data from thousands of records, you might flush the buffer every 100 records, so that the end user sees some results earlier and you don&#8217;t tax the server&#8217;s memory.<\/p>\n<p><strong>Disadvantage of <strong>Response.Flush<\/strong>:<\/strong><\/p>\n<p>You can use the\u00a0<strong>Response.Flush<\/strong> method. This method sends output up to that point to the client. Note that clients that connect over slow networks where buffering is turned off, affect the response time of your server. The response time of your server is affected because your server needs to wait for acknowledgements from the client. The acknowledgements from the client occur after the client receives all the content from the server.<\/p>\n<p>For more info, you can read below articles:<\/p>\n<p><a href=\"http:\/\/msdn.microsoft.com\/en-us\/library\/ff647787.aspx\" target=\"_blank\">Improving ASP.NET Performance<\/a><\/p>\n<p><a href=\"http:\/\/msdn.microsoft.com\/en-us\/library\/ms525560(VS.90).aspx\" target=\"_blank\">Response.Flush Method<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Usage of Response.Flush method in ASP.NET, its disadvantage and advantage of buffering in IIS.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"advanced_seo_description":"","jetpack_seo_html_title":"","jetpack_seo_noindex":false,"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"jz_research_post":"","_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[21],"tags":[43],"class_list":["post-908","post","type-post","status-publish","format-standard","hentry","category-net","tag-asp-net"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":71,"url":"https:\/\/www.jitendrazaa.com\/blog\/webtech\/web\/style-file-upload-control-in-asp-html\/","url_meta":{"origin":908,"position":0},"title":"Style File upload control in ASP \/ HTML","author":"Jitendra","date":"May 10, 2010","format":false,"excerpt":"As most of us know that we cannot style the file upload control to much level, still we can give it a stunning effect with the help of CSS.
