Hello *,
When downloading a cached file from the local squid, I just get about
250 - 280kB/s. Even on localhost. Is this a limitation with diskd
serving files from cache or some intern limit? I also tried aufs, but
didn't get a better rate. I found a thread here about this, but it got
more into a diskd/aufs discussion :) and didn't provide a solution or
explains it. It doesn't look like it's disk/system related,
vmstat/top doesn't show
high load.

TIA, ritch
I too have experience this. I believe this is because Squid has
built-in safeguards to keep users from flooding the disk and to even
the load across all disks for all users. Another reason is Squid
handles all requests in sequential order--client requests, server
requests, and memory/disk cache reads/writes.. It is like a
virtualized network handler or VM. It really doesn't want one client
to kill all others..
HTH,

Btw, it still does have a lot to do with diskd/aufs... Read here
