Our server is performing decently, but when backups or other scan processes run it will tank the entire server. Something like
clamd will run and scan many files. While we expect slow performance, it's killing our cache and the end result is we don't get a system that can do anything.
Is there a way to disable disc/disk caching for a single command? The idea would be to run it like this:
# ./nocache clamd
Then while running
clamd it would not thrash the primed cache while reading all the files on the system.
