HI all, I have met one problem:
There is one big file(600MB) and it is very hot, it is larger than ` ram_cache_cutoff ` setup: CONFIG proxy.config.cache.ram_cache_cutoff INT 20M I have noticed that the `rKB/s` on one disk is very high, and the disk usage is keeping nearly 100%. Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sde 0.00 124.00 196.33 2.33 47210.00 505.33 480.36 35.17 182.13 5.02 99.73 It seems linux pagecache does NOT work when using ATS, and ATS ram_cache does not work either, am I correct? What is the suggestion value of `proxy.config.cache.ram_cache.size` and `proxy.config.cache.ram_cache_cutoff` ? How should I handle this case? Thanks in advance. --- Best Regards, Thomas
