Default Faster PHP

Hi every one,
I have server working under OpenBSD, but php scripts work sloww. If I would make /var/www/tmp folder in RAM, would it be any faster ?
Or is there any way to make it work faster ?

Maybe; maybe not. You have not characterized what the script is doing.

I would first suggest becoming familiar with the output of top(1) to ascertain whether the application is unduly chewing up CPU or swap space. top(1) will provide an indication whether adding RAM will help alleviate congestion.

In the same vane, study the output of swapctl(8) which will indicate how much the system is swapping out to swap space. Again, an inordinate amount indicates that the system is starved for RAM.

Next, study the output of iostat(8) & fstat(1) to determine the script is I/O-bound & whether the files in question reside in /var/www/tmp. Looking at the output of df(1) may provide additional context.

Effectively improving performance requires understanding multiple metrics. Without knowing more, moving /var/www/tmp to RAM may indeed make the situation worse.

Server dosen't use swap, there is 800 MB of RAM free.
CPU is 2.8 Ghz, Intel Pentium 4, usually it's almost not loaded at all.

How to make PHP scripts run faster?

Use C or ASM to do the leg work (like all of it :P)


beyond that, it's the same problem as always.... study, tune, tweak, test, ....

Does it use a database? First thing that comes to mind is that the database is the bottleneck.

Yes, it does.

Nicely encapsulated where-to start to look.

Thanks,
