I happy you’re sharing you thoughts and indeed i was, and still is surprised by my numbers. Just tested it again this morning:
Indeed the results are depending on what kind of network i am located at running the test. Having enough bandwith to press the setup.
If you find any flaws on my demosite please let me know if i missed something. - It’s demo and ment to be tested…
I’m not quite sure on how you calculate the 600Kb page size ?

He is not lying about the results he is getting. I have also tested it from my local system (see below).
However, it doesn’t look like ‘genuine’ results, not that he is being deliberately misleading, but I am only on a 10MB connection here and I shouldn’t be able to download data at this pace.
In the past, I have customised mod_evasive to serve ‘HTTP1.1 200 OK’ headers, instead of the default ‘HTTP1.1 403 Forbidden’. That way, as far as ab is concerned - it is completing transactions at a phenomenal rate.
Looking at the amount of files Magento loads without an opcode cache (25MB per page!), its a huge IO hog. Add in an opcode cache and its more like 5MB of cache it hits, if said server was completing 420 RPS, you would be looking at a sustained (not burstable) IO read speed of around 2GB p/s. On the other hand, network alone, on an average of 600kb for the demo store homepage at 420 RPS we’re talking 252MB p/s (2 Gb p/s) sustained.
I’ve got to say, if its genuine - I would love to see the complete configuration.
Below is the ab output, attached is the page size breakdown.

Not a big fan of numbers and calculations so I just tested their demo as an actual user would and I must say it is the fastest Magento store up until now.
So who cares about numbers?

Hi, I am using memcached as backend, and it is working. But I just have a feeling it is not working properly because -
when I use memcache.php to check, it says the cache usage is only 0.5MBytes.
256MBytes were allocated to memcached. As Magento is a big programme, I expect it uses up lots of memory for caching. Can anyone tell me what reasonable cache size is for a store with about 300 products?

Thanks a lot!
How do your app/etc/local.xml file look ?
And have you enabled caching in magento->system->cache mangement ?
<memcached><!-- memcached cache backend related config --> <servers><!-- any number of server nodes can be included --> <server> <host><![CDATA[127.0.0.1]]></host> <port><![CDATA[11211]]></port> <persistent><![CDATA[1]]></persistent> </server> </servers> <compression><![CDATA[0]]></compression> <cache_dir><![CDATA[]]></cache_dir> <hashed_directory_level><![CDATA[]]></hashed_directory_level> <hashed_directory_umask><![CDATA[]]></hashed_directory_umask> <file_name_prefix><![CDATA[]]></file_name_prefix> </memcached> </cache>
Yes, I have enabled Cache in System -> Cache Management
