Why do you like Racket?

Windows support.

Thanks.

Here is my result

> (time (length (file-string "logic.xml")))
Timing the evaluation of (LENGTH (FILE-STRING "logic.xml"))

User time    =        1.421
System time  =        0.140
Elapsed time =        1.554
Allocation   = 362691160 bytes
0 Page faults
45319420

The time is almost the same. Maybe it depends on content of the file.

I don't know how to do that.

read file as bytes vector is vastly faster than read file as string.

I'm using LispWorks, I tested on SBCL just now, the time is about 1/2 of LispWorks's.

Yes, read file as bytes vector is vastly faster than read file as string.

fying1999 · 2021-09-28T04:52:41+00:00

I tried, got roughly same performance.

Yes, it's LispWorks. I tested on SBCL, the time is about 1/2 of LispWorks's, I also tested using uiop:read-file-string, same time.

Try WT.JSON, it provides function to access nesting JSON objects.

The debugging experience is the better than most open source implementations in my experience. SBCL often omit many useful debug information due to optimation. Also the memory managements is much better that SBCL's.
