Kohana vs Codeigniter, Performance Synthetics

I want to compare the performance of two amazing (and, in my humble opinion, amazing) frameworks, Kohana and Codeigniter . The test is synthetic, but, it seems to me, still interesting.

Test conditions

In both frameworks I did not use view, but only work inside controllers. DB: Postgresql 8.3 on localhost. Both controllers have the simplest form.
In the first test, there was a simple cycle in 333 iterations, inside which a call to the database was launched by the following request:

SELECT *
FROM tbl_clients
JOIN tbl_clients_recvisites ON tbl_clients.clientid = tbl_clients_recvisites.clientid
JOIN tbl_recvisites ON tbl_clients_recvisites.recvisiteid = tbl_recvisites.recvisiteid
JOIN tbl_clients_contacts ON tbl_clients.clientid = tbl_clients_contacts.clientid
JOIN tbl_contacts ON tbl_clients_contacts.contactid = tbl_contacts.contactid

* This source code was highlighted with Source Code Highlighter.

Additionally, a profiler integrated in both controllers was included.
The second test used Apache JMeter

Test one - pure synthetics without emulation

On each of the frameworks, I repeated the actions 10 times (10 times [F5]) and recorded the results of the application (delivery time is not taken into account - only PHP work ). Results in the table:

	Codeigniter	Kohana
1	26,6959	14,808
2	26,6049	14,178
3	27,5487	14,289
4	26.7427	13,845
5	26,6099	14,554
6	26,5644	14,381
7	26.9622	13,717
8	26.8828	14,242
9	27.2445	13,771
10	26.8514	14,479
Average	26.87	14.23

And further. Important note : Codeigniter consumed 1.74MB of RAM in this test, and Kohana - 1.35MB

Test Two - Approaching Reality

This test used JMeter to simulate concurrent requests.
The test was as follows. For each of the subjects (CI and KOH), 10 simultaneous threads were sent with 5 requests each (in the thread they will be executed in turn), but in order not to “kill” the stand, the number of database queries was reduced from 333 to 9 (well yes, I love the number 3;))
In the first case, the framework gave the profiler data, but they turned out to be different in the amount of bytes transmitted, so I conducted the second series of tests when both frameworks gave only 2 bytes ('ok') after the work was done. Each test was run in JMeter 3 times. Summary
Tables:
Codeigniter 9 Query Profiler Enabled

Average (ms)	Min (ms)	Max. (ms)	Throughput (requests / sec)	Kb / s
3880	2492	4370	2,5	57.17
3729	2538	4105	2.6	59.5
3760	2608	4263	2.6	59.04

Kohana 9 profiler requests enabled

Codeigniter 9 queries,'ok 'output

Average (ms)	Min (ms)	Max. (ms)	Throughput (requests / sec)	Kb / s

Kohana 9 searches, output'ok '

Average (ms)	Min (ms)	Max. (ms)	Throughput (requests / sec)	Kb / s

2445	997	2924	3.9	0.01
2448	1266	2883	3.9	0.01

As can be seen from these tables, the number of bytes given during application operation did not affect in any way.

conclusions

Everyone makes conclusions for himself, I just decided to test such similar, but at the same time different frameworks. For myself, I seem to have made it.
In no case do not forget that for each work there is the most suitable tool for it ...
