Problem with Tie::File

[Spyke212]

Hi,

I have a script that accesses a file using Tie::File, and then loops through all 52,000 lines, analysing the data.
(The file is around 500mb in size)

However, there is a problem, my program gets gradually slower the longer it runs, and after about 2,000 lines it nearly comes to a complete standstill.

I have tried using the memory=> command that accompanies File:Tie, but even boosting it to 10000_00000_0000 doesnt stop it from slowing down.

Does anyone know the reason why?

Many thanks

S

Yes, your perl program is doing something very cpu/memory intensive, that is causing it to slow down. Try writing a simpler script and add to it until you get to the point where you program starts slowing down. That should give you a hint where the problem is.

if you're only reading the file, why use Tie::File, it's a bit overkill for a file that size for that functionality
