I changed asset cache settings. assets stored in s3 bucket and cached using squid.

in a month, 43.7 million requests with avg 2.8ms latency, but using over 70% inodes on root, which is a concern, so i moved cache directory to dedicated 1tb drive.

previous:

Filesystem Inodes in use: 41617829/58391712 (71%)


current:

Percent Used: 27.37%
Filemap bits in use: 1181346 of 2097152 (56%)
Filesystem Space in use: 224359048/921816860 KB (24%)
Filesystem Inodes in use: 1189583/58720032 (2%)

inodes to 2% is a good improvement. I increased the size of RAM cache a bit from 32GB to 48Gb which should help decrease latency.

no assets were harmed during this production. hehe
