jk2625 opened a new issue #2058: URL: https://github.com/apache/incubator-pagespeed-mod/issues/2058
We're seeing issues (across multiple websites with different content) with ModPagespeed v1.13.35.2-0 on Apache/2.4.6 causing significant TTFB delays (~600-700ms in total) on websites with somewhat larger HTML content (> 100kb or so). This only happens when: 1. ModPagespeed is turned on (disabling via ?ModPagespeed=off fixes this) 2. Brotli compression via mod_brotli is on and compressing the HTML Normal TTFB is roughly 100-200ms in total. This happens regardless of what filters are enabled - setting it to pass through and/or disabling all active filters still causes the same delay. ModPagespeedHttpCacheCompressionLevel 0 has been tried too. /var/cache/mod_pagespeed/v3 is currently 93M, /var/cache/mod_pagespeed/shm_metadata_cache is currently 5.3M Both are local filesystems - not using Memcache.
