Hello, 
Thanks for your response...On similar lines, I have another query: 

I have a folder with SNP data totaling up to 288.0 Mb.All of this data will be ONE SINGLE TRACK on gbrowse2. 
Now, I have atleast 10 other tracks being shown, including two "genes" track from different sources...so its a lot of data.
I realize that my system seems to slow down while rendering tracks.. I am not able to render the SNP track when I choose the whole chromosome view. I am only able to visualize snps when I zoom into a region less than 1MB in size. 

I will be trying to load the snps onto a totally new database for improvement in speed to some extent. 
apart from that I have already turned on slaves just for the snps. 

(It took me 20 minutes to write this email as the system had stopped responding because I tried to look at snps in a region greater than 10 Mb. I can safely say that 1Mb is a clear region for viewing snps. After this, the glyphs start to clump together and showthemselves as a big dark patch. 

I would lik eto knwo the following:
1. is "Semantic Zooming" the colution to this problem/

am I supposed to add any additional functions to the config file?


Apart from this I also will be loading another track with snps from another source which may be the same file size. 

Thanks, 
Pushkala
