RE: [squid-users] Tweaking Squid for higher performance

Hi,

What version would you advise from the following example:

Ver1. 3x Cache_dir 16GB each on different SCSI disks
Ver2. 1x Cache_dir 48GB on HW RAID-0

Regards,

Yuri Fominov

in order for squid to reach 1000 request per second, you need to
redesign squid from scratch... squid starting to degrade itself when it
reaches greater than 100 request per second... since squid is a single
thread, it wont scale to higher loads... multi-threading or parallelism
is the key for squid to reach your expected throughput aside from better
filesystem design for http objects...

> or what I can do to increase performance

since squid is a single thread and using either select() or poll()
function, you are bound by the limitation of these two functions... that
is why the bottleneck of squid is on its disk i/o system... if you want
to increase its performance, make a RAM filesystem instead of disk
filesystem for its web cache.... but of course you already know the pros
and cons of using RAM filesystem :->
