dennisjac commented on issue #1639: Values on statistics page not updated URL: https://github.com/apache/incubator-pagespeed-ngx/issues/1639#issuecomment-479008203 This is what my configuration looks like: ``` Options AvoidRenamingIntrospectiveJavascript (aris) True BeaconUrl (bu) /ngx_pagespeed_beacon EnableRewriting (e) 1 FileCacheCleanIntervalMs (afcci) 3600000 FileCacheInodeLimit (afcl) 500000 FileCachePath (afcp) /var/cache/nginx/ngx_pagespeed_cache FileCacheSizeKb (afc) 10485760 LRUCacheByteLimit (alcb) 32768 LRUCacheKbPerProcess (alcp) 16384 RespectXForwardedProto (rxfp) True RewriteLevel (l) Core Filters StatisticsPath (nsp) /ngx_pagespeed_statistics ``` The documentation says that if no explicit shared-memory cache is specified there is a default one that will be used. What are the appropriate values for the cache sizes? The file cache directory is currently 7GB in size but the default shared-memory cache in only 50MB which seems tiny. On the other hand if I would increase this to say 5GB (the server has 16GB of RAM) then the snapshotting would probably cause massive disk i/o when all of this is written out. For some reason pagespeed is causing around 200 write IOPS for no apparent reason and my hope is that by configuring the in-memory caching correctly that I can fix this issue. It seems unlikely that pagespeed is updating so many files all the time so I suspect it might have something to do with metadata.
