Related to Marc's suggestion, if you have SAS on the same computer as R, try
the sas.get function in the Hmisc package.
I know it doesn't help you, but I have not had speed issues with haven.

Subject: Re: [R] Importing SAS datasets into R efficiently
Hi,
'foreign' will only read SAS XPT files, not the proprietary BDAT files, which I
presume is the case here.
I don't use 'haven', but it looks like the key functions are written in C/C++,
which should be relatively efficient.
If you are having specific issues with particular files, because they are
rather large, and/or have some kind of complex structure, you might want to
communicate directly with the haven maintainers to see if there are some
performance bottlenecks that perhaps they can resolve.
The only other option, to my knowledge, to directly read BDAT files in R, is
the sas7bdat package on CRAN:
https://cran.r-project.org/web/packages/sas7bdat/
<https://cran.r-project.org/web/packages/sas7bdat/>
CRAN - Package sas7bdat
cran.r-project.org
sas7bdat: SAS Database Reader (experimental) Read SAS files in the sas7bdat
data format.
CRAN - Package sas7bdat
cran.r-project.org
sas7bdat: SAS Database Reader (experimental) Read SAS files in the sas7bdat
data format.
However, it looks like it has not been updated in several years, so not sure of
status.
Another alternative, if you have access to SAS, is to export the BDAT
datasets(s) to CSV files in SAS, and them import them into R, using read.csv().

Marc Schwartz
