I added crispEdges and optimizeSpeed to the polyline and the result was
that time to display around 5000 points was reduced to a fraction of a
second from 4 - 5 seconds.
About the last point you mentioned
-don't use polylines, use paths with relative stroking (lower case
letter path commands)
Is path faster and also if i use relative (i.e. Lower case letter commands
like M 10 10 l 20 30 l 30 20) coordinates will it make the rendering even
more fast ???.

[svg-developers] Re: Performance problem while setAttribute("points") on
polyline
You're right,
the asv rendering engine is dead slow. Try to lower demands on
viewer:
-set xxx-rendering="optimizeSpeed", at least shape-
rendering="crispEdges" (probably you'll know already;-)
-asv antialiasing is very expensive, set defaultAntialias="false",
or use .setDefaultAntialias(false) while updating dom and revert
to .setDefaultAntialias(true) when finished
-don't use classes for styling, inline attribs should process
faster (nasty adice;-)
-don't use polylines, use paths with relative stroking (lower case
letter path commands)
