conandrum edited a comment on issue #1882: Pagespeed rating drops after a couple of hours? Why? URL: https://github.com/apache/incubator-pagespeed-mod/issues/1882#issuecomment-491028928 Thanks for replying: I have read that page when setting things up. My test site is http://134.209.247.233/ (no domain, no SSL, no traffic) This is why I chose to my setup as follows: ``` ModPagespeed on AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER text/html ModPagespeedFileCachePath "/var/cache/mod_pagespeed/" ModPagespeedLogDir "/var/log/pagespeed" ModPagespeedSslCertDirectory "/etc/ssl/certs" ModPagespeedStatisticsLogging on ModPagespeedEnableCachePurge on ModPagespeedPurgeMethod PURGE ModPagespeedFileCacheSizeKb 2048000 ModPagespeedFileCacheCleanIntervalMs 3600000 ModPagespeedFileCacheInodeLimit 500000 ModPagespeedDefaultSharedMemoryCacheKB 50000 ModPagespeedImageMaxRewritesAtOnce -1 ModPagespeedLoadFromFileCacheTtlMs 31536000000 ModPagespeedLoadFromFileMatch "^https?://134.209.247.233/" "/home/hallonpower/public_html/" ModPagespeedLoadFromFileRuleMatch disallow .* ModPagespeedLoadFromFileRuleMatch allow \.css$ ModPagespeedLoadFromFileRuleMatch allow \.jpe?g$ ModPagespeedLoadFromFileRuleMatch allow \.png$ ModPagespeedLoadFromFileRuleMatch allow \.gif$ ModPagespeedLoadFromFileRuleMatch allow \.js$ ModPagespeedLoadFromFileRuleMatch allow \.svg$ ModPagespeedDisallow "*/admin/*" ModPagespeedFetchHttps enable ModPagespeedRewriteLevel CoreFilters ModPagespeedEnableFilters remove_comments,collapse_whitespace,elide_attributes,trim_urls ModPagespeedDomain http://fonts.googleapis.com ModPagespeedGoogleFontCssInlineMaxBytes 20000 ModPagespeedEnableFilters inline_google_font_css ModPagespeedEnableFilters lazyload_images ModPagespeedEnableFilters responsive_images ModPagespeedEnableFilters responsive_images_zoom ModPagespeedEnableFilters insert_image_dimensions ``` https://www.modpagespeed.com/doc/faq#varying-results states: There are two (relatively) common situations that may lead up to a fluctuating level of optimization in the output: 1. Low traffic (TRUE FOR THIS TEST SITE - test was without traffic for 2 hours) short http expiry times for image, css and javascript (increase the http expiry or set up LoadFromFile) ModPagespeedFileCacheCleanIntervalMs 3600000 ModPagespeedLoadFromFileMatch "^https?://134.209.247.233/" "/home/hallonpower/public_html/" ModPagespeedLoadFromFileCacheTtlMs 31536000000 2. High cache churn rates: caches are sized too small, (Size the cache to 3 to 4 times the size of the original assets) ModPagespeedFileCacheSizeKb 2048000 ModPagespeedFileCacheInodeLimit 500000 ModPagespeedDefaultSharedMemoryCacheKB 50000 3. If the above did not help, the admin pages offer various tools that may assist in diagnosing what happens. Question: 1. ModPagespeedFileCacheCleanIntervalMs 3600000 = 1 hour If I increase this to 86400000 (24 hours) this should stop early expiry? 2. ModPagespeedDefaultSharedMemoryCacheKB 50000 How do I know if this is enough or not? 3. Anything else you see that I may be doing wrong? Been playing with pagespeed for only a week.
