Large file read to AutoIt again but faster


Recommended Posts

Posted (edited)

I have some large file which I have to read to AutoIt to make some checking but reading same file again and again take a lot of time. I was wondering if I can save that file in some other way to read it in Autoit faster? It's report (text file) with tab character column separator. Maybe I can save it in RAM or something?

Any idea?

There aren't many details in your request. How are you currently reading the file? Have you looked into using FileReadToArray or _FileReadToArray?

My code use FileRead, StringSplit and some loop to convert file to array but I just tried _FileReadToArray and it's very fast. Instead of 60sec I wait now about 1-2 sec. That is incredible change! Thank you very much!

It is all about speed. I am wondering if I can load data from file into AutoIt array with same fast way as function _FileReadToArray() do but with json file.

Local $hFileOpen = FileOpen($sFilePath)
Local $sJson_FileRead = FileRead($hFileOpen)

Local $oJson_Orders = Json_Decode($sJson_FileRead)
Local $a_oJson_Orders = Json_ObjGet($oJson_Orders, "orders")

So how long do these 4 lines actually take to run?
Do you have something to share that is "slow" and we can see/run/test with?
