Title: Crawler Server Load Limit on shared CloudLinux Last modified: April 29, 2026 --- # Crawler Server Load Limit on shared CloudLinux * [goldensw](https://wordpress.org/support/users/goldensw/) * (@goldensw) * [6 days, 19 hours ago](https://wordpress.org/support/topic/crawler-server-load-limit-on-shared-cloudlinux/) * Hi, I’m running LSCache WordPress plugin on shared hosting with LiteSpeed Enterprise and CloudLinux/CageFS isolation . The crawler works correctly, but I noticed that the **Server Load Limit** setting evaluates the **global server load average**, not the per-account load within my LVE. * From my understanding, this makes the setting effectively unusable in shared CloudLinux environments: - On shared CloudLinux, the global load is dominated by other tenants’ activity, which I have no visibility into or control over. - A conservative value would block my crawler permanently (global baseline often exceeds it). - A high value effectively disables the protection and the setting becomes cosmetic. - CloudLinux LVE limits already throttle my account independently, so I can’t actually overload the server from my side regardless of crawler activity. * **Questions:** 1. Is there a way to make Server Load Limit evaluate **per-account** resource usage( CPU, EP, IOPS within the LVE) instead of global server load average? 2. Is there a server-side variable, filter, or `wp-config.php` constant that changes how the threshold is interpreted on CloudLinux? 3. If no such option exists, is this a known limitation, and is there any roadmap consideration for shared/CloudLinux-aware load detection? * For context: my hosting plan has dedicated LVE limits (CPU, EP, IOPS, memory), and CloudLinux automatically throttles overuse. The crawler workload is small( ~280 URLs, ~70s per cycle) and well within my plan’s capacity, but the load limit setting offers no meaningful control in this environment. * Any guidance is appreciated.

One follow-up thought: cPanel already reads per-account CPU/memory/IOPS usage in real-time from CloudLinux LVE and displays it in Resource Usage. Would it be feasible in any way for the crawler to use those same per- account metrics instead of global load average? The data is already there, it’s just not being used by the crawler. * Plugin Support [litetim](https://wordpress.org/support/users/litetim/) * (@litetim) * [6 days, 12 hours ago](https://wordpress.org/support/topic/crawler-server-load-limit-on-shared-cloudlinux/#post-18894614) * [@goldensw](https://wordpress.org/support/users/goldensw/) I think the difference stands in how CPANEL and PHP reads the CPU usage. We are using: [https://www.php.net/manual/en/function.sys-getloadavg.php](https://www.php.net/manual/en/function.sys-getloadavg.php) to read current load.The code will try to look for usage based on server user ID.
