Which texteditor for very large textfiles

Hello everybody

For quite a while now I am searching for a plain-text editor which is capable of "handling" very large textfiles. So what kind of files do you need that for, you might ask. Well, as an amateur astronomer my telescope automatically creates textfiles every 3 minutes (or so) with all the data you need to find specific objects in a specified region of the sky. Meanwhile this file is as big as 4,5 GB and Texteditor does not like files of this size. It takes hours to load this file. Once loaded, Texteditor isn't responsive at all: a search of a specific string or word once again takes hours. So I was wondering if there is a simple text editor which is capable to handle these gigantic files. I tried MacVim, but its response is as bad as texteditor.

Hope someone can help me out.

Thanks for your time, anyway.

I'd prefer BBEdit for this, but depends on how much RAM you have, how much of it is used, how much free speed on your HDD, and if your HDD is in fact an HDD or an SSD...

Thank YOU ALL for your quick and adequate answers which all pointed to one solution: use BBEdit. This really is a workhorse, seemingly without effort ploughing through loads and loads of textstrings. 4GB file, 20 GB RAM and ssd took 35 seconds! Way-way-way faster than the 4 -5 hours (?? I stopped counting) Textedit needed. The version I downloaded first wasn't compatible with my vintage 27" iMac, but lucky for me older versions are available for download too.

So, once again a big THANK YOU.
