[galaxy-user] Job running speed is really slow

Dear Galaxy team, I found glalaxy (website) is running really slow today. I just did some text manipulations over a very small file. It takes a long time till the gray colour (waiting) turns into yellow (running). Now the jobs are still waiting to be processed (gray colour). I have to analyze my RNA-Seq data next weeks. If the speed continues to be like this, I am sure it is not possible to finish the analysis, since these files are really large. Could you please let me know what I should do to speed it up? Thanks, Jiwen
