Browser seems slow

There are various factors that could make the browser appear to have slow behavior. Here are suggested ways to test the browser performance.

Check network connection

Verify browser address can be found, unix command: host genome.ucsc.edu

$ host genome.ucsc.edu
genome.ucsc.edu is an alias for genome.soe.ucsc.edu.
genome.soe.ucsc.edu has address 128.114.119.131
genome.soe.ucsc.edu has address 128.114.119.132

Verify network path is available to the browser: ping -c 3 genome.ucsc.edu

$ ping -c 3 genome.ucsc.edu
PING genome.soe.ucsc.edu (128.114.119.131) 56(84) bytes of data.
64 bytes from hgw1.soe.ucsc.edu (128.114.119.131): icmp_seq=1 ttl=43 time=170 ms
64 bytes from hgw1.soe.ucsc.edu (128.114.119.131): icmp_seq=2 ttl=43 time=170 ms
64 bytes from hgw1.soe.ucsc.edu (128.114.119.131): icmp_seq=3 ttl=43 time=170 ms

--- genome.soe.ucsc.edu ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2000ms
rtt min/avg/max/mdev = 170.361/170.370/170.378/0.007 ms
