Benchmark of generated C source code from asn1c and asn1tools.
The asn1c executable is a lot bigger than asn1tools and asn1scc because it contains encode and decode functions for all codecs, not only uper as for asn1tools and asn1scc. There is no asn1c option to only generate uper code. asn1c also supports more ASN.1 construts and uses dynamic memory.
asn1tools:
text data bss dec hex filename 5553 560 8 6121 17e9 main
asn1scc:
text data bss dec hex filename 12073 560 8 12641 3161 main
asn1c:
text data bss dec hex filename 63733 4904 80 68717 10c6d main
Encoding and decoding the PDU type 1,000,000 times for each tool and optimization combination.
| Tool | Optimization | Exexution time [s] |
|---|---|---|
| asn1tools | -O3 | 1.229 |
| asn1tools | -Os | 2.987 |
| asn1scc | -O3 | 4.023 |
| asn1scc | -Os | 6.166 |
| asn1c | -O3 | 10.902 |
| asn1c | -Os | 12.569 |
asn1tools has the fewest lines of code, only 832. asn1scc has 3549 and asn1c 10159.
The statistics was created with cloc.
