Follow up on Benchmarking results for 3.1.10 vs 2.7.9

Hi,

 I have some benchmarking numbers that I would like to share with the community.
These numbers are from 2 servers that have the exact same hardware configuration
in the same data center receiving the same type of requests (not the best setup
for a SQUID server but that is a different story).

The server spec is below follwed by the benchmark numbers. I am looking to
improving the 3.1.10 config or adjust RHEL4 in efforts to reduce the CPU
consumption and improve hits. I will follow up with any improvements or findings
that find interesting.

Server Spec:

CPU: Dual Intel(R) Xeon(R) CPU L5310 @ 1.60GHz Quad Core
Mem: 4GB
HD: 450 SATA
OS: Red Hat Enterprise Linux AS release 4 (Nahant Update 4) 32-bit, OS has been

tuned for 32-bit & RHEL 4.4

Squid Object Cache: Version 3.1.10-20101227
Users: 57
RPS: 1409
Hit Ratio Request: 36.3%, 36.4% , Byte: 47.6%, 48.6%
CPU Usage: 51.63%

Squid Object Cache: Version 2.7.STABLE9-20100923
Users: 55
RPS: 1419
Hit Ratio Request: 44.6%, 44.9% , Byte: 47.7%, 48.5%
CPU Usage: 33.42%

All comments and questions welcomed.

Thanks,

Jack

Hi,

I wanted to share some benchmarking results from one of the nodes in live system

running the

3.1.9 build line. I also plan in installing the 3.1.10 line within the next week

after verification of the newer build. I will share the results if the show
improvements.

If you have any questions or comments please feel free to ask.

CPU Intel(R) Xeon(R) CPU L5310 @ 1.60GHz (dual-core)
RAM 8 GB
HDD 1 x 400G SAS
OS Red Hat Enterprise Linux AS release 4 (Nahant Update 4) 32-bit, OS has been
tunned for 32-bit & RHEL

Users 54
RPS 615
Hit Ratio Request 41.7%-42.8% , Byte 49.8.7%-46.9%
CPU Usage 31.69%

Thanks,
