Hello,
R 4.1.0 on Ubuntu 20.04, sessionInfo at the end.
I'm arriving a bit late to this thread but here are the timings I'm
getting on an 10+ years old PC.
1. I am not getting anything even close to 5 or 10 mins running times.
2. Like Bill said, there seems to be a caching effect, the first r

Dear Bill,
Does list.files() always sort the results?
It seems so. The option: full.names = FALSE does not have any effect:
the results seem always sorted.
Maybe it is better to process the files in an unsorted order: as stored
on the disk?
Sincerely,
Leonard

What kind of disk do you use? The hardware differences might be important
to this issue.
Best,

Dear Bill,
- using the Ms Windows Properties: ~ 15 s;
[Windows new start, 1st operation, bulk size]
- using R / file.info() (2nd operation): still 523.6 s
[and R seems mostly unresponsive during this time]
Unfortunately, I do not know how to clear any cache.
[The cache may play a role only
On a $150 second-hand laptop with 0.9GB of library,
and a single-user installation of R so only one place to look
LIBRARY=$HOME/R/x86_64-pc-linux-gnu-library/4.0
cd $LIBRARY
echo "kbytes package"
du -sk * | sort -k1n
took 150 msec to report the disc space needed for every package.

On Sun,
On my Windows 10 laptop I see evidence of the operating system caching
information about recently accessed files. This makes it hard to say how
the speed might be improved. Is there a way to clear this cache?

Dear List Members,
I tried to compute the file sizes of each installed package and the
process is terribly slow.
It took ~ 10 minutes for 512 packages / 1.6 GB total size of files.
1.) Package Sizes
system.time({
x = size.pkg(file=NULL);
})
# elapsed time: 509 s !!!
# 512 Packages
