Bug ID: 15590
Summary: GDB slows nonlinearly as number of inferior solibs
increases
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: shlibs
Assignee: unassigned at sourceware dot org
Reporter: gbenson at redhat dot com
Performance testing during the implementation of the probes-based runtime
linker interface revealed that GDB slows nonlinearly as the number of inferior
shared libraries increases:
no of solibs 128 256 512 1024 2048 4096
-----------------------------------------------------------------
original interface 0 1 4 12 47 185
probes interface 0 0 2 4 10 36
(time in seconds)
The probes interface is considerably faster than the original, but there is
still some nonlinearity there.
