From e2d47e2f75bac6876b7c2eaecfe946966bf27516 Mon Sep 17 00:00:00 2001 From: Liu Jinsong <jinsong.liu@intel.com> Date: Tue, 26 Nov 2013 04:53:17 +0800 Subject: [PATCH] VMX: wbinvd when vmentry under UC This patch flush cache when vmentry back to UC guest, to prevent cache polluted by hypervisor access guest memory during UC mode. However, wbinvd is a _very_ time consuming operation, so 1.

And? $ time mkdir -p /bin real 0m0.002s user 0m0.000s sys 0m0.002s an extra mkdir takes around 2ms per build. An up-to-date inc build takes 2231ms for me. If you want some of the extra 2231ms back, I'd recommend avoiding recursion in the makefiles. This will yield a larger benefit than worrying about the extra mkdir. If we have it, then .dir files are created in the installation...

...he board increase in response times. It seems that every call to memcache now takes 10x longer than before. Here are some example numbers from my development log (below), with memcache running locally. We see similar scale of performance drop in production as well - average memcache call before 2ms, now 20ms. It adds up to a significant hit. Before Rails 2.3 upgrade: Cached fragment hit: views/homepage_recent_blog_posts (0.00043) Cached fragment hit: views/homepage_active_threads (0.00033) Cached fragment hit: views/homepage_weekly_feature (0.00029) Cached fragment hit: views/homepage_rece...

...Authenticate header 3. Asterisk re-sends INVITE to OpenSIPs with Proxy-Authorization header, but has the wrong password 4. goto step 2 and repeat forever So what we're seeing is Asterisk re-sending an INVITE with incorrect auth (which is clearly never going to work), about every 2ms. The Call-ID remains the same all of the time. Shouldn't PJSIP realise that this isn't going to work after a few tries and give up? The only way I've found of stopping the seemingly infinite loop is to either restart Asterisk or temporarily block network traffic between the two machi...

...egress interface eth0 of the router at any stage. (every packet is enqueued by pfifo_enqueue() to an empty queue. I have confirmed this by adding adding a counter in sch_fifo.c that is incremented every time there is a packet in the queue when a new packet is enqueued.) The delay is at a maximum of 2ms. When I increase the policing rate and shaping rates to 48.4687. The combined increase is 31.2 kbit which is very small. there are some packets queued for a short period and some dropped which clears the queue. The maximum number of packets dropped was 20 per second. But the delay goes up to 30ms...

...sk box on-site. Each site has an 8mb down/448k up ADSL connection and the phones connect via SIP to an asterisk box in a datacentre using g729. The asterisk box in the datacentre connects to our other asterisk boxes providing pstn connectivity via IAX2. Latency between these boxes is between 1 and 2ms. The ADSL connections to the client sites are all consistently delivering latencies of sub-25ms to the datacentre and there is traffic shaping on that connection to give priority to any traffic from the phones' IPs. Comments from the users at these sites are as follows: "call sounded like...

I''m trying out rails 3 and I''m looking at the performance statistics given by WEBrick. It says many of my database operations are taking 2ms or 7ms... but the view is taking 40ms. People often say that the database is the bottleneck in applications (which it most certainly can be, and often is)... but isn''t the rendering of ERB a little show here? My test pages really aren''t that complicated... 1 partial... 1 layout......
