Dynamic CSS takes a long time to load

As I already wrote in the title, dynamic CSS take a long time to load, which is around 1 second. The connection is not the problem because I am testing this plugin on a local WordPress installation.

I am talking about this request: <link rel=’stylesheet’ id=’wpdiscuz-dynamic-css-css’ href=’http://192.168.0.13/wp-admin/admin-ajax.php?action=dynamicCss&ver=3.0.6&#8242; type=’text/css’ media=’all’ />,

which results with this CSS code:

#wpcomm .wc_new_comment{ background:#136FD2;} #wpcomm .wc_new_reply{background:#136FD2;} #wpcomm .wc-form-wrapper{background:#FFFFFF;} #wpcomm select, #wpcomm textarea, #wpcomm input[type="text"], #wpcomm input[type="email"], #wpcomm input[type="url"]{ border:#F1F1F1 1px solid;} #wpcomm .wc-comment .wc-comment-right{ background:#FFFFFF;} #wpcomm .wc-reply .wc-comment-right{ background:#FFFFFF; } #wpcomm .wc-comment-text{ font-size:14px;color:#000000;} #wpcomm .wc-blog-post_author > .wc-comment-right .wc-comment-author, #wpcomm .wc-blog-post_author > .wc-comment-right .wc-comment-author a{ color:#D21313;} #wpcomm .wc-blog-post_author > .wc-comment-left .wc-comment-label{background:#D21313;}#wpcomm .wc-blog-administrator > .wc-comment-right .wc-comment-author, #wpcomm .wc-blog-administrator > .wc-comment-right .wc-comment-author a{ color:#000000;} #wpcomm .wc-blog-administrator > .wc-comment-left .wc-comment-label{background:#000000;}#wpcomm .wc-blog-editor > .wc-comment-right .wc-comment-author, #wpcomm .wc-blog-editor > .wc-comment-right .wc-comment-author a{ color:#000000;} #wpcomm .wc-blog-editor > .wc-comment-left .wc-comment-label{background:#000000;}#wpcomm .wc-blog-author > .wc-comment-right .wc-comment-author, #wpcomm .wc-blog-author > .wc-comment-right .wc-comment-author a{ color:#000000;} #wpcomm .wc-blog-author > .wc-comment-left .wc-comment-label{background:#000000;}#wpcomm .wc-blog-contributor > .wc-comment-right .wc-comment-author, #wpcomm .wc-blog-contributor > .wc-comment-right .wc-comment-author a{ color:#000000;} #wpcomm .wc-blog-contributor > .wc-comment-left .wc-comment-label{background:#000000;}#wpcomm .wc-blog-subscriber > .wc-comment-right .wc-comment-author, #wpcomm .wc-blog-subscriber > .wc-comment-right .wc-comment-author a{ color:#000000;} #wpcomm .wc-blog-subscriber > .wc-comment-left .wc-comment-label{background:#000000;}#wpcomm .wc-blog-ap_moderator > .wc-comment-right .wc-comment-author, #wpcomm .wc-blog-ap_moderator > .wc-comment-right .wc-comment-author a{ color:#000000;} #wpcomm .wc-blog-ap_moderator > .wc-comment-left .wc-comment-label{background:#000000;}#wpcomm .wc-blog-ap_participant > .wc-comment-right .wc-comment-author, #wpcomm .wc-blog-ap_participant > .wc-comment-right .wc-comment-author a{ color:#000000;} #wpcomm .wc-blog-ap_participant > .wc-comment-left .wc-comment-label{background:#000000;}#wpcomm .wc-blog-betteroptin > .wc-comment-right .wc-comment-author, #wpcomm .wc-blog-betteroptin > .wc-comment-right .wc-comment-author a{ color:#000000;} #wpcomm .wc-blog-betteroptin > .wc-comment-left .wc-comment-label{background:#000000;}#wpcomm .wc-blog-guest > .wc-comment-right .wc-comment-author, #wpcomm .wc-blog-guest > .wc-comment-right .wc-comment-author a{ color:#000000;} #wpcomm .wc-blog-guest > .wc-comment-left .wc-comment-label{background:#000000;} #wpcomm .wc-comment-footer a, #wpcomm .wc-comment-footer span.wc_editable_comment,  #wpcomm .wc-comment-footer span.wc_save_edited_comment, #wpcomm span.wc_cancel_edit { color:#A9A9A9; } #wpcomm .wc-comment-footer .wc-vote-result{ background:#A9A9A9;} #wpcomm .wc-reply-link, #wpcomm .wc-vote-link, #wpcomm .wc-share-link {color: #A9A9A9; }.wc-load-more-submit {border: 1px solid #F1F1F1;} #wc_openModalFormAction > div#wc_response_info a.close {  background: url("http://192.168.0.13/wp-content/plugins/wpdiscuz/assets/img/x.png") no-repeat;}#wpcomm .wc-new-loaded-comment > .wc-comment-right {background: #FFFFFF;} .comments-area { width: auto; margin: 0 auto; margin-top: 100px; } .wpdiscuz-front-actions{ background:#FFFFFF;  } .wpdiscuz-subscribe-bar{ background:#FFFFFF;  } .wpdiscuz-sort-buttons{ color:#A9A9A9; } .wpdiscuz-sort-button{ color:#A9A9A9; cursor:pointer; } .wpdiscuz-sort-button:hover{ color: #136FD2; cursor:pointer; } .wpdiscuz-sort-button-active{ color: #136FD2!important; cursor:default!important; }#wpcomm .page-numbers{ color:#000000; border:#000000 1px solid; } #wpcomm span.current{ background:#000000; }

Do you know why is it so slow and if it can be improved to load faster?
