High performance

[Andrea A]

Hi all,
I have a question:
what do you think about performance (only performance not style,
functionality, and so on) comparing PHP 4 and PHP 5.
Which version is better if one want to develop a small website with a lot
lot of page views (all pages are dynamic)?

Hi,

In all likelihood you won't notice any difference in performance,
though PHP5 is supposed to be faster in certain areas. I would suggest
building your site, and then trying to optimize any bottlenecks such
as database access. For instance, cutting down on unnecessary round-
trips to the database, and perhaps using persistent connections. You
can also cache certain portions of your site that don't have to be re-
generated with every page view.

Which is the best method to cache?

What about memcached?

thanks,

Depends on the server. Connecting to a MySQL server for example is
pretty cheap, while persistent connections may cause you a lot of
troubles. Don't do that unless you really need it and know what you're
doing.

5.2 comes with an improved memory manager, which did speed up things
here. Using a bytecode cache like APC might be worth a look as well.

Re: High performance

One way is to use PEAR Cache:

can also cache certain portions of your site that don't have to be re-
generated with every page view.

I think this might be a problem I'm having. I'm trying to monitor/tail
some log files and perform queries to 1) insert the new data, 2)
verify that the data is within certain constraints.

I'm not closing the connections, I'm guessing this would be considered
persistent (just to make sure I'm understanding--not a big DB guy)?
I just didn't want to keep openning and closing connections.

Each query is taking a full second to perform (is that normal? I have
about 100k records at the moment).

Plus, having an issue with only able to tail two files...?
I'm using Apache server, PHP (ver4) driven pages, querying a MySQL DB.
I can open two Internet Explorer windows and tail two files; but as
soon as I try to open a 3rd, nothing happens until I get out of one of
the others.

Any idea to why I can only do 2 at a time?

Thanks
