For 200-300 hits/s (ca 20-30Mbps of HTTP traffic) you need to quite a
bit of tuning, and design your system correctly. This is about as
fast as it is practically possible to build a single Squid proxy
server today with correct tuning.
Sidenote: reverse proxies may have a higher workload and perform fine,
depending on the workload size.
* You need several cache drives and use aufs/diskd (which to use
depends on your OS). Squid puts a quite high load on harddrive seek
times.
* You need to tune your system for many filedescriptors. 200-300
hits/s you will certainly run into the default limit of 1024
filedescriptors/process after a while. Depending on your OS type you
also may need to tune the max number of sockets open, network I/O
buffers etc.
* You need to reconfigure the system to have many unbound TCP/IP ports
available for applications to use. At these rates you need to have a
range of unbound TCP/IP ports of at least 30000 ports, preferably the
double (max possible).
* Also make sure to read the Squid FAQ chapter on memory usage.
