Php 5.1.0

[orban]

Anybody compiled that yet? :) Tempting, they claim a lot of performance improvements.

[kerplunk]

We're using it with APC 3.0.8. There is a HUGE speed difference between PHP 5.0 and PHP 5.1. Zend Engine 2 is very nice. I would strongly recommend upgrading to PHP 5.1.

[orban]

Nice to hear!

Does it work with eAccelerator 0.9.4-rc1 (http://sourceforge.net/mailarchive/forum.php?thread_id=9027313&forum_id=43418)?

kerplunk, how's speed between PHP 5.1.0 vs PHP 4.4.1 ?

according to the eaccelerator forum - nope.

I think I give APC a try... what are the differences to eaccelerator ?

[orban]

I'm interested in that too. I used eAcc in the past and it really works/worked great.

i try to make some benchmarks on my development box .. I want to test:

php 4.4.1 (without accelerator)
php 4.4.1 eaccelerator
php 4.4.1 apc
php 5.1 (without accelerator)
php 5.1 apc

It's a small box ( i think a 600 mhz amd duron or something like that running freebsd ) but it should be ok for comparison.

I plan to use apache ab on the same box for benchmarking.

[orban]

Apache 2 or 1 and PHP compiled as apxs?

[DaFire]

ok .. I made a few tests now:

Apache 2.0.55
./configure --enable-so

php 4.4.1 & php 5.1.0
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr --with-gd --with-zlib-dir=/usr/lib

I called the benchmark tool with

/usr/local/apache2/bin/ab -n 100 localhost/forum/index.php
(100 requests)

I ran all tests twice after restarting the server to make sure the caches are already filled

My conclusion after the first test is that plain php5.1 is a bit slower than php 4.4.1 but using apc its slightly faster.

[orban]

eAcc coming soon? :D

eAcc with PHP 5.0.5 and 4.xx that is.

And thanks a lot!

[Scott MacVicar]

Use APC, its written by one of the core PHP developers (who works for Yahoo where its also used)

[Tantawi]

I upgraded too and it works great with APC 3.0.8.

[orban]

I really have to check out APC then :)

APC user here as well. :)

excellent comparison there :)

[DaFire]

I have seen benchmarks where the difference between php4/php5 and php5.1 are huge ... php5.1 a few times faster then the older ones but I guess in a real life situation ( the page i benchmarked is forum frontpage with vbadvanced cmps boxes on the left side ) the things that count are database server and those still run with the same speed :)

[version2]

Performance-wise...does it make sense to go ahead and move on to php5?

It appears so. We're running PHP 5.1.1 with APC and it's awesome. :)
