Issues

[Rosie White]

Hi I’ve been having some trouble running Antconc when I use a large data set (around 700 .txt files) it works on about 100 files but slows / freezes when I try to do much more. I am working on a MacBook with only 4GB of RAM do you think this could be the issue? If so how much RAM do you think I would need? If you have any other tips on speeding things up & improving performance with large data sets I’d appreciate it. (Processor of comp is 1.4 GHz intel i5). Many thanks for your wonderful software!

I have an 8gb RAM and a corpora of 1 Million words. This works perfect. Hope it helps.

Try an older version like 2.5.3 which is using lighter code. The links are on Lawrence’s site, here:

Anything before 2.5.4 is fast. If memory serves me correctly 2.4.1 is the version which was least buggy. 

Good luck.

Hi Rosie,

If you have a MacBook with only 4GB of RAM, I suspect much of that RAM is being used to run the operating system. So, you won't have much left to see results.

The problem will not be related to the number of files that you are looking at, though. There are only two things that affect the performance of AntConc:

1) The size of the file. AntConc has to open a file and read it before any processing can occur. If any one of files is very large requiring a lot of memory to read, that can cause AntConc to slow or freeze.

2) The number results generated. AntConc has to show the all the results of a search on the screen which takes up memory. If you generate many, many results that can also impact on the performance.

Try searching for a rare term with your 700 files and you should see that it works fine. If it doesn't, it means that the problem is probably 1) above.

I hope that helps.

Regards,

Laurence.

Thank you I will give all of these a try. KB/MB wise what would count as a big file? Will manually scan through the corpus and see if there is any 1 file tripping it up.

Hi Rosie,

Just take your folder of files, sort them by size, and then take the smallest say 200 files and test them. If it works, you'll know that the number of files is not the problem.

Laurence.
