[squid-users] Scalability in serving large ammount of concurrent requests

[Roy M.]

In http://highscalability.com/youtube-architecture , under "Serving
Thumbnails", it said:

..
- Used squid (reverse proxy) in front of Apache. This worked for a
while, but as load increased performance eventually decreased. Went
from 300 requests/second to 20.
..

So does it mean squid is not suitable for serving large ammount of
concurrent requests (as compare to apache)


Thanks.
