Performance!

In my MIX talk I told that for 2k reads, we take 3ms. It is actually the case under load where the servers are straining. Here is a latest performance shot that we got with the CTP3 bits.

Bulk APIs: Note that these numbers are without any bulk operations. With bulk gets (we are trying to add a Bulk Get in RTM timeframe within a region) we get upwards of 211,000 operations per second. (assuming a 32 key per batch).

Local Cache: None of these tests use Local Cache = true. That will again give upwards of 200K operations per second.

[Statutory Warning: These are the numbers that we got in our test labs to give you an idea of the performance characteristics of this product. There is no implicit warranty or guarantee on these numbers!]

Servers : 2

Server Configuration :

Processor : AMD Phenom (9600 B) Quad Core Processor

RAM size : 8 GB RAM

Operating System : 64 bit win 2k3

Network : 1GBPS network

Secondary : 0

Client configuration : Routing with NO local cache.

No of Agents : 10

Throughput :

Scenario	object	Number of Clients	RC4(Ops/sec)	CTP2(Ops/sec)
Mainly Gets	Byte[] (2kb)	100	34500	36300
Mainly Gets	Byte[](2kb to 16kb)	150	27000	27300
Put	Char[](2kb)	200	9170	6060
Put-Get	String[](1kb)	200	11500	8000
Put-Get-Remove	Byte[](4kb) wrapped in object	100	30300	29880

Latency :

Operation(byte array)	Object	RC4(In ms)	CTP2(in ms)
Add	Char [](2kb)	1.35	1.59
Put	Byte [](2kb)	0.63	0.55

Trending with and without secondary throughput on RC4:
