2.4.19-UP-RSBAC-v1.2.1-Celeron-333-256MB
These Linux kernel compile benchmarks have been run on an Celeron-333 UP system with kernel 2.4.19 and RSBAC version 1.2.1.
Three runs each of 'make clean && time make bzImage' on the same plain 2.4.19 kernel source tree in single user mode after one untimed run produced the following average times in seconds:
| Kernel type | Total time | Kernel/Sys + User | Kernel/Sys time | User/Process time |
|---|---|---|---|---|
| Clean kernel | 747.97 | 745.85 | 34.68 | 711.17 |
| Maint kernel (no modules) | 753.09 (+0.68%) | 750.94 (+0.67%) | 38.61 (+11.33%) | 712.33 (+0.16%) |
| RC + AUTH, no other options | 758.62 (+1.42%) | 756.55 (+1.43%) | 44.89 (+29.44%) | 711.66 (+0.07%) |
| RC + AUTH, network support, full log settings, no other options | 765.18 (+2.30%) | 761.47 (+2.08%) | 49.60 (+43.02%) | 711.87 (+0.10%) |
| RC + AUTH + ACL, network support, full log settings, no other options | 773.22 (+3.38%) | 769.85 (+3.20%) | 59.12 (+70.47%) | 710.73 (-0.06%) |
| Default config: REG, FF, AUTH, RC, ACL, CAP, JAIL, network support, full log settings, but nothing logged | 779.46 (+4.21%) | 777.25 (+4.19%) | 63.28 (+82.47%) | 713.97 (+0.39%) |
| All options and models | 820.00 (+9.63%) | 816.97 (+9.52%) | 103.83 (+199.39%) | 713.14 (+0.28%) |
Numbers have not changed much from the previous benchmark. RC and AUTH are now with and without full network and logging options. Since the MS model was doing fine in the last benchmark, it had no extra runs this time.
With all models and options, 1.2.1 was a bit faster now than 1.2.0-pre6 was without MS and JAIL. Less than 10% overhead with all options sounds good enough to me.
