Linux 4.x Tracing Tools: Using BPF Superpowers
Talk for USENIX LISA 2016 by Brendan Gregg. "Linux 4.x Tracing Tools: Using BPF Superpowers The Linux 4.x series heralds a new era of Linux performance analysis, with the long-awaited integration of a programmable tracer: Enhanced BPF (eBPF). Formally the Berkeley Packet Filter, BPF has been enhanced in Linux to provide system tracing capabilities, and integrates with dynamic tracing (kprobes and
Designing SSD-Friendly Applications for Better Application Performance and Higher IO Efficiency
These days, solid state drives (SSD) are being increasingly adopted to alleviate the I/O performance bottlenecks of applications. Numerous measurement results have showcased the performance improvement brought by SSD as compared with hard disk drives (HDD). However, in most deployment scenarios, a SSD is simply treated as a “faster HDD.” Hence, the potential of SSDs is not fully utilized. Although
