We will increase the limit to 512KB in future release, is that large enough?
That is the size limit of signle XML entry, it is fine as long as the total size of one group of rewrite rules is not over the limit. Rewrite rules in .htaccess does not have this limit.
Apache's rewrite engine is not very efficient, so I expect big performance boost for web sites using a lot of rewrite rules when switching to lsws, hope you can share the result with us. thanks.
