Hi,
I'm testing ATS works as forwarding proxy, after few hours, I found the
number of Cache miss was too high:
$ sudo ./traffic_logstats -s | grep Cache
Cache hit 15 0.24% 243.13KB
0.21%
Cache hit IMS 10 0.16% 1.92KB
0.00%
Cache hit refresh 123 1.97% 8.48MB
7.42%
Cache hit other 0 0.00% 0.00KB
0.00%
Cache hit total 148 2.37% 8.72MB
7.62%
Cache miss 4,918 78.90% 77.91MB
68.13%
Cache miss IMS 829 13.30% 869.13KB
0.74%
Cache miss refresh 14 0.22% 32.70KB
0.03%
Cache miss other 0 0.00% 0.00KB
0.00%
Cache miss total 5,761 92.43% 78.79MB
68.90%
My records.config
CONFIG proxy.config.http.cache.ignore_client_no_cache INT 0
CONFIG proxy.config.http.cache.ims_on_client_no_cache INT 0
CONFIG proxy.config.http.cache.ignore_server_no_cache INT 0
CONFIG proxy.config.http.cache.required_headers INT 2
CONFIG proxy.config.http.cache.max_stale_age INT 604800
CONFIG proxy.config.http.cache.range.lookup INT 1
In the logging, found some static contents was cached, eg.
http://pastebin.com/vV9MRCLF but others was not.
Can somebody help me figure out what is my problem please?
Additional, I defined 1GB Ram cache
CONFIG proxy.config.cache.ram_cache.size INT 2147483648
but I see not much RAM was used, could I prefer Ram cache than Disk cache?
Thank you and best regards,
