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 126.96.36.199 genome.soe.ucsc.edu has address 188.8.131.52
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 (184.108.40.206) 56(84) bytes of data. 64 bytes from hgw1.soe.ucsc.edu (220.127.116.11): icmp_seq=1 ttl=43 time=170 ms 64 bytes from hgw1.soe.ucsc.edu (18.104.22.168): icmp_seq=2 ttl=43 time=170 ms 64 bytes from hgw1.soe.ucsc.edu (22.214.171.124): 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
