Better use Firefox now, I was also using Chrome till its 29th version and after that it is getting slower and slower, now into Firefox and its working smoothly...
or what is slower. Startup time ? Page loading time ? issue with too many tabs making slower ? did you check memory manager in chrome/chromium to report memory usage - comparison with other browser ?
Pick up a SRware iron build(which is a stripped-down version of chrome and very similar to chromium) - It has no reaching google servers thing enabled [ SRWare Iron - Wikipedia, the free encyclopedia ] - germans are more strict on their privacy concerns and seemingly a german group maintains this. Privacy and no unnecessary connecting to google servers.
above + opendns should keep things good.
Happy Surfing!
