Subject: Performance - linking against DPDK shared vs static libraries
Date: Wed, 23 Jul 2014 15:58:06 +0000	[thread overview]
Message-ID: <DC5AD7FA266D86499789B1BCAEC715F846BA3C50@IRSMSX105.ger.corp.intel.com> (raw)

Hi,

I build a switching application, which links against DPDK shared libraries; when I run the application, I see throughput of X.  I then build the application again, except this time I link against DPDK shared libraries, having modified the application's build parameters appropriately.  In this case, I see a performance drop of around .04%, which given the high throughput of the application is significant.

Is such performance degradation to be expected when using DPDK shared libraries, and if not, are there any best-known methods for preventing performance degradation, assuming that I may be constrained to using shared libraries going forward?

Thanks,
Mark
