<div dir="ltr"><div>Hi all<br><br></div>My Xymon server 4.3.10 is burning the CPU cycles when we view multiple graphs, like the trends page, and takes about 5 seconds to render a single graph in a single-graph page view.<br>
<br clear="all"><div><div>It's a Sun Fire X4150 with 4Gb of RAM, running Solaris 10 update 5..<br><span style="font-family:courier new,monospace"><br>Version Location Tag<br>-------------------------------- --------------------------<br>

</div><div>It's been slow since it was installed. <br>If I view the trends column, I can see the CPU load jump from below 1 to over 10 at times.<br></div><div>Running prstat or top in another window while viewing the trends column, the process ranking by CPU gets dominated by showgraph.cgi, owned by the web server user. <br>
