Title: CPU usage – delay time – notfication – Version Last modified: August 20, 2016 --- # CPU usage – delay time – notfication – Version * Resolved [Senymedia](https://wordpress.org/support/users/senymedia/) * (@senymedia) * [13 years, 1 month ago](https://wordpress.org/support/topic/cpu-usage-delay-time-notfication/) * After using the free plugin we’ve bought the PRO version. As this is a fine working plugin, fast and easy… * Though my hosting provider denied my IP address after a day, saying there was a spammer active on my own IP address. What appeared to be a fine working plugin has a small glitch, it uses way too much CPU-power. * After emailing and even using the chat on the developers own website there was no reaction, so here are my questions: * – It seems that when active on the WP Live Chat page in WordPress there is a request for update every second (This part gained the CPU usage with >15%). It is a kind of logic, as you’ll need to check if there are users on the chat. Will it help to change the **wplc_auto_refresh** in ms to reduce the refresh frequency? * – The notification we receive is only active on the Live Chat page, again where it appears doesn’t change the fact that it needs refreshing. Sending an email will be the other solution but we can not check our mail every minute… and therefore the user on the other side needs to wait at least a minute before there will be a reaction from us. * – The Pro version is still 2.1, is this correct? * What are the options? And how can we resolve the high CPU loads of this plugin? * [http://wordpress.org/extend/plugins/wp-live-chat-support/](http://wordpress.org/extend/plugins/wp-live-chat-support/) Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Author [WP-LiveChat](https://wordpress.org/support/users/wp-livechat/) * (@wp-livechat) * [12 years, 10 months ago](https://wordpress.org/support/topic/cpu-usage-delay-time-notfication/#post-3480834) * Hi We’ve noticed the high CPU load on certain hosts and we are trying to get around this. The only reason this is happening is because the plugin is designed so that your own server is used as the chat server and not a 3rd party server. * I’m looking into smarter ways of handling the ajax calls between the user and the server as well as the admin and the server. * Kind regards Nick * [nemocool](https://wordpress.org/support/users/nemocool/) * (@nemocool) * [12 years, 10 months ago](https://wordpress.org/support/topic/cpu-usage-delay-time-notfication/#post-3480835) * Hi * I have the same problem. Why don’t you block the purchase of your plugin. It is not ready yet. High CPU load is a nightmare and then we are charged more by the hosting provider. * [nemocool](https://wordpress.org/support/users/nemocool/) * (@nemocool) * [12 years, 10 months ago](https://wordpress.org/support/topic/cpu-usage-delay-time-notfication/#post-3480836) * Ok for the time being I’m switching to [http://screets.com/dev/projects/wordpress-live-chat-for-sales-and-support/](http://screets.com/dev/projects/wordpress-live-chat-for-sales-and-support/) When do you think you will update to ajax? * Plugin Author [WP-LiveChat](https://wordpress.org/support/users/wp-livechat/) * (@wp-livechat) * [12 years, 10 months ago](https://wordpress.org/support/topic/cpu-usage-delay-time-notfication/#post-3480837) * Hi nemocool & Senymedia We’re just about to launch version 2.4 which has considerable performance improvements. * We’ve reduced the latency by 55%. Therefore, were websites used to take around 2200ms to send the ajax request and receive a response, it now takes around 980ms. Obviously this all depends on your hosting environment and it could be even quicker. The benchmark is that on a localhost server, the ajax request and response should take around 40ms. * We’ll continue to try and improve on this as time goes by. * Kind regards Nick * Plugin Author [WP-LiveChat](https://wordpress.org/support/users/wp-livechat/) * (@wp-livechat) * [12 years, 10 months ago](https://wordpress.org/support/topic/cpu-usage-delay-time-notfication/#post-3480838) * Quick edit: The response time I gave about was for a distant country. For country to country communication, your’re looking at a response time of less than 200ms * [WPGMaps](https://wordpress.org/support/users/wpgmaps/) * (@wpgmaps) * [12 years, 10 months ago](https://wordpress.org/support/topic/cpu-usage-delay-time-notfication/#post-3480839) * I see version 2.5 is live * Plugin Author [WP-LiveChat](https://wordpress.org/support/users/wp-livechat/) * (@wp-livechat) * [12 years, 10 months ago](https://wordpress.org/support/topic/cpu-usage-delay-time-notfication/#post-3480840) * That’s correct.
