Name

high_page_fault_warning

Synopsis

If you provide a nonzero value for this directive, Squid periodically checks the process page fault rate. Page faults generally occur when the Squid process doesn’t fit entirely in memory. A moderate number of page faults can significantly degrade performance. If the one-minute average rate (page faults per second) exceeds this threshold, Squid prints a warning message in cache.log.
